Ramadan

I’tikaaf, its meaning, virtues and masaa’il

Says Allama Ibn Qaiyyim Radiallâhu anhu: “The basic purpose of I’tikaf is that the heart gets attached to Allâh and, with it, one attains inner composure and equanimity and pre?occupation with the mundane things of life ceases and absorption in the eternal Reality takes its place, and the state is reached in which all fears, hopes and apprehensions are superseded by the love and remembrance of Allâh, every anxiety is transformed into the anxiety for Him and every thought and feeling is blended with the eagerness to gain His nearness and to earn His good favour, and devotion to the Almighty is generated instead of devotion to the world and it becomes the provision for the grave where there will be neither a friend nor a helper. This is the high aim and purpose of I’tikaf which is the speciality of the most sublime part of Ramadhân, i.e., the last ten days.”

Similarly, Hadhrat Shah Waliullah Radiallâhu anhu remarks, “Since I’tikaf in the masjid is a means to the attainment of peace of the mind and purification of the heart, and it affords an excellent opportunity for forging an indentity with the angels and having a share in the blissfulnes of the Night of Power and for devoting oneself to prayer and meditation Allâh has set apart the last ten days of the month of Ramadhân for it and made it a Sunnah for His pious and virtuous slaves.”
Rasulullâh Sallallâhu ‘alayhi wasallam always observed, I’tikaf and the Muslims have on the whole adhered to it. It has become a regular feature of the month of Ramadhân and a confirmed practice with the devout and the faithful. Hazrat Ayesha Radiallâhu anharelates that “Rasulullâh. Sallallâhu ‘alayhi wasallam regularly observed I’tikaf during the last ten days of Ramadhân till the end of his life. After him, his wives maintained the tradition.” (Bukhari)
It is related by Hazrat Abû Huraira Radiallâhu anhu that “Rasulullâh Sallallâhu ‘alayhi wasallam observed I’tikaf for ten days every year in the month of Ramadhân. In the year he passed away he observed it for twenty days.” (Bukhari)

MEANING OF I’TIKAF

The reality of I’tikaf is that a person remains in the masjid for a certain period with the intention [niyyah] of I’tikaf. There is no time limit pres­cribed for whatever time is spent in the masjid with the intention of I’tikaf such spending of time will constitute I’tikaf. However, a period of ten days is prescribed for the Masnun I’tikaf of Ramadhân ? the Sunnah will not be fulfilled for a period less than ten days. In the case ofI’tikaf Wâjib (that’ is, a person who has taken a vow to perform I’tikaf, it cannot be fulfilled in a period less than one day and one night. (Badai)

WHO MAY PERFORM I’TIKAF
1. It is necessary for I’tikaf that a person be a Muslim and sane. Hence, the I’tikaf of an insane person or a kafir will not be valid. However, just as a minor child may perform Salâh or keep fast, similary such minor may perform I’tikaf. (Badai).
2. A woman may also perform I’tikaf in her home by setting aside a specified place for ibâdah and performing therein such I’tikaf. However, it is necessary for her to obtain her husband’s consent for such I’tikaf. Moreover, it is essential that she is not in a state of menstruation and nifâs.
3. it is a condition of I’tikaf Masnun and I’tikaf wâjib that a person be in a state of fasting. Hence, if a person is not in a state of fasting, he cannot perform these categories of I’tikaf. However, fasting is not a condition in the case of Nafl I’tikaf.

PLACE OF I’TIKAF

For male persons, ‘Itikat can only be performed in the masjid. The most blessed and preferred I’tikaf is that performed at al?Masjid alHarâm in Makkah. The next most preferred I’tikaf is that performed at al?Masjid al?Nabawî in al?Madinah. Third in order of preferability is al?Masjid al Aqsa (in Al?Quds). Fourthly, any Jam’i Masjid. However, it is not neces­sary to perform I’tikaf at a Jam’i Masjid. On the contrary, I’tikaf may be performed at any masjid where prayers are said five times (each day) in jama’at. If a masjid is such that five time prayers (each day) are not said therein, then in such an event there is a difference of opinion amongst the ‘Ulamâ’. Some scholars are of the view that I’tikaf may be performed at such a masjid, although it is not preferable. (Shâmi)

I’tikaf can be made in a masjid wherein only in Ramadhân 5 daily Salâh are performed (Fatâwa Rahîmîyah vol. 2. p. 30)

TYPES OF I’TIKAF

I’tikaf Masnun ? This refers to that I’tikaf which is only performed in the month of Ramadhân during the last ten days thereof commencing on the twenty?first night and terminating upon the sighting of the the moon of Shawwal (that is, on the eve of ‘Id al?Fitr) It is termed I’tikaf Masnun because Rasulullâh Sallallâhu ‘alayhi wasallam performed I’tikaf every year in these days.

I’tikaf Nafl ? This refers to that ‘Itikaf which may be performed at any time.
I’tikaf Wâjib ? This refers to that I’tikaf
(a) which becomes wâjib because of making nadhr, that is, taking a vow, or
(b) which becomes wâjib as Qada’ for rendering void a Masnun I’tikaf.
MEANING AND EFFECT OF MASNUN I’TIKAF
TheI’tikaf which is performed in the last ten days of Ramadhân Mubarak is known as Masnun I’tikaf. The time for this I’tikaf commences upon completion of the twentieth day (of Ramadhân), that is, with effect from the setting of the sun, and remains until the sighting of the Shawwal moon (Eid moon). In view of the fact this I’tikaf commences from the twenty?first night (of Ramadhân) ? and the night commencing from the setting of the sun ? it is therefore necessary for the person wishing to performI’tikaf to enter the hudud of themasjid on the twentieth day on such time before Maghrib so that the setting of the sun takes place whilst he is in the masjid.
The I’tikaf of the last ten days of Ramadhân is Sunnah Mu’akkadah Kifayah. This means that if one person, who lives in a particular area in which a masjid is situated, performs I’tikaf, then in such an event the Sunnah is fulfilled on behalf of all the members of that area. However, if nobody in the entire area performs I’tikaf, then all the members of the area will be liable for the sin of failing to fulfil a Sunnah.
RESPONSIBILITY OF MEMBERS OF AN AREA AND MAIN FEATURE OF I’TIKAF
1.   It is clear from the foregoing that it is the responsibility of every member of the area or township to ascertain in the beginning whether any person is to sit for the I’tkâf in their masjid or not.
2.   However, it is not permissible to cause some person to sit by giving him payment or money because it is not permissible in the case of ‘Ibadah to give or take money or wages. (Shâmi)
If no member of a particular area is able to sit forI’tikaf due to circumstan­ces of necessity, then in that event arrangements must be made to cause some person from another area to sit. (Fatâwa Darul Ulûm Deoband)
The outstanding pillar of I’tikaf is that a person remains for the duration of I’tikaf within the hudûd of the masjid. Save and except for the necessities of nature (see details later), he must not leave the hudud of the masjid even for one moment. For, if he leaves thehudûd of the masjid for one moment without a valid Shar’î reason (the details of which are dealt with later), the I’tikaf is rendered void.

LEAVING THE MASNUN ON THE GROUNDS OF SHAR’ΠNECESSITY

By the term Shar’î necessity, we mean those necessities on the basis of which the Sharî‘ah has permitted the person performing I’tikafto leave the masjid. TheI’tikaf is not rendered void if the person leaves by virtue of such necessities.

These necessities are as follows:

1.   The need to urinate or defecate, that is, to attend to the call of nature.

2.   The need for Ghusl of janabah when it is not possible to make Ghusl in the masjid.
3.   The need to make wudhu when it is not possible to make wudhu while in the masjid.
4.   The need to bring food and drink when another person is not available to do so.
5.   The need of the Mu’adhin to go out for the purpose of calling Adhân.
6.   If Jumuah Salâh is not performed in the masjid wherein I’tikaf is performed, the need to go to another masjid to perform Jumu’ah.
7.   The need to move to another masjid in the event of leaking, etc. of the the masjid.
Apart from these needs, it is not permisible for the person performing I’tikaf to leave the masjid for any other purpose. Now, we shall,insha-Allâh, explain details of each of these needs.
CALL OF NATURE
(a)  The person performingI’tikaf can leave the rnasjid to attend the call of nature, that is, to urinate of defaecate. In so far as urinating is concerned, he must go to the place nearest the masjid where it is possible to urinate. In regard to defaecation, if a toilet has been built attached to the masjid, and if it is possible to defaecate therein, then he must go there. It is not permissi­ble to go to another place. However, if a person cannot defaecate due to his nature or because of extreme difficulty at any place besides his home, then it is permissible forlim to go to his house for this purpose, even if a toilet is available near the triasjid. (Shâmi)
If a person does not have this difficulty, then he should utilise the toilet of the masjid. If such a person leaves the masjid toilet and goes to his house, then his I’tikaf is rendered void according to some ‘‘Ulamâ. (Shâmi)
(b)  If the masjid does not have any toilet, or if it is not possible to attend the call of nature therein, or in the case of extreme difficulty, then in such events it is permissible to go home to attend the call of nature, notwith­standing the distance of such home. (Shâmi)
(c)  If the home of a friend or a relative is present near the masjid, it is not necessary to go to his friend’s or relative’s home to attend the call of nature. Despite this, one is permitted to go to one’s home even if it is situated at a distance in comparison to the home of such a friend or a relative. (Shâmi)
(d)  If a person owns two houses then he should go to the nearer one to attend the call of nature. If he goes to the further home then his I’tikaf is rendered void according to some ‘ulama. (Alamgiri)
(e)  If the toilet is occupied, then it is permissible to wait until it is vacant. But it is not permissible to remain even for one moment once the need is fulfilled. If one remains then, I’tikaf is rendered void. (Barjandi)
(f)  It is permissible to make Salâm to someone or to reply to a Salâm or to talk briefly in the house or on the way to the toilet and on return, provided that one does not stop for such brief talk. (Mirqat)
(g)  It is not necessary to walk briskly on the way to the toilet or on return. It is permissible also to walk slowly. (Âlamghiri)
(h)  On the way to the toilet to attend to the call of nature, one must not stop at the instance of another. One must while walking indicate to such other person that one is in a state of I’tikaf. One can not stop for this purpose. If one stopped for some time at the instance of another, then his I’tikaf is rendered void. This applies to the extent that if a debtor has on the road stopped the person performing I’tikaf then according to Imâm Abû Hanifah Rahmatullâh ‘alayhi the I’tikaf is rendered void. The I’tikaf is not rendered void by virtue of his necessity according to Imâm Abû Yusuf and Imâm Muhammad Rahmatullâh ‘alayhi. Imâm Sarakasi Rahmatullâh ‘alayhihas on the basis of ease and facility manifested a preference for the view point of the latter two. (Mabsut) However, precaution demands that one must not stop on the road under any circumstances.
(i)   It is permissible to smoke a cigarette upon leaving to visit the toilet provided that one does not have to stop for this purpose.
(j)  If any person who has gone to his house for the purpose of attending to the call of nature, then it is permissible for him to make wudu therein, after attending to the call of nature. (Majma?ul?Anhar)
(k)  Istinjah is included in the term “attending to call of nature”. Hence, if a person suffers from the disease of urine drops, he can go outside for the purpose only of Istinjah for this reason, the jurists have set forth Istinjah as a separate ground of necessity entitling a person to leave apart from the ground of “attending to the call of nature.” (Shâmi)
(l)   While in I’tikaf to be in state of wudhu is Mustahab [desirable] and not wâjib [compulsory]. To read books of Tafsîr and jurisprudence in the state of wudhu is also mustahab. (Fatâwa Mehmoodiya vol. 3 p. 117/2)
(m) While in I’tikaf one can inquire from vistors about those who are absent. (ibid.)

GHUSL

It is permissible for the person performing I’tikaf to leave the masjid for the purpose of Ghusl of Janabah in the event of emission of semen.

This is subject to the explanation that if such a person can make Ghusl whilst remaining in the masjid, for example, by sitting in some big tub and performing Ghusl in a manner that the water does not fall in the masjid then it is not permissible for him to go outside.
However, if this is not possible or there is extreme difficulty then he may go outside for Ghusl of Janabah. (Fath?ul?Qadir) If there is aGhusl Khanah in the masjid, then he must perform Ghusl there. However, if there is no Ghusl Khana in the masjid, or it is not possibleto make Ghusl therein for some reason, or if there is extreme hardship, then one can perform Ghusl in one’s home.
Apart from Ghusl of Janabah, it is not permissible to leave the masjid for any other Ghusi. It is not permissible to leave the masjid for the purpose of Jurnu’ah Ghusl or a Ghusl to cool oneself. If one has left the masjid for this purpose then I’tikaf is rendered void. However, if one wishes to make Jumu’ah Ghusl or cool oneself, then he must adopt such a course that the water does not drip into themasjid. For example, he must sit in some tub and bathe himself, or make Ghusl at the corner of the masjid in such a way that the water drips outside the masjid.

EATING

If a person has another available to bring food and water for him to the masjid, then it is not permissible for such a person performingI’tikaf to leave the masjid for the purpose of fetching food. If, however, he does not have available any person to bring food and water, then it is permissible for him to leave the masjid to bring food (al?Bahr?ur?Raiq). However, the food must be brought to the masjid and eaten therein. (Kifayat?ul?Mufti)

Such a person moreover must bear in mind that he must leave the masjid at a time when he is able to receive the food. But if he has to wait for some reason to receive the food, there is no objection.
ADHÂN
(a)  If a mu’adhin is performing I’tikaf and he has to leave the masjid for the purpose of giving Adhân, then it is permissible for him to go outside. But he must not remain there after giving the Adhân.
(b)  If a person is not a mu’adhin but he wishes to give Adhân for a particular time, then it is permissible for him to leave the masjidfor the purpose of giving Adhân. (Mabsut)
(c)  If the door of the minaret of the masjid is situated within the masjid, then it is absolutely permissible for the person performingI’tikaf to climb the minaret because it will constitute part of the masjid. However, if the door of the masjid is outside the masjid itself, then apart from the need to give Adhân, the person performing ’ltikaf is not permitted to climb such a minaret. (Shâmi)
(d)  It is preferable that I’tikaf be made in such a masjid where Jumu’ah Salâh is performed so that it is not necessary to go outside forJumu’ah. However, if no Jum’ah Salâh is said in a particular masjid and only five times Salâh is said therein, then it is permissible to perform I’tikaf in such a muffid. (Âlamghiri)
(e)  In such a situation, it is permissible to go to another masjid to perform Jum’ah Salâh. However, one must leave for this purpose at such a time that, in his estimation, upon reaching the Jam’i Masjid, he will be able to perform the four rakâh sunnah and thereafter, witness immediately the commencement of the khutbah. (ibid.)
(f) If the person performing I’tikaf has gone to a certain masjid to perform Jurn’ah, then he may perform sunnah prayers after completing the fard in that masjid. However, he cannot remain (in the masjid) thereafter. (Ibid). If he remains for a period exceeding necessity then his I’tikaf is not rendered void because he has remained in a masjid. (Badai)
(g) If a person goes to a Jam’i Masjid to perform Jum’ah and thereafter remains there and completes the remaining period of I’tikaf, then his I’tikaf will remain valid. This act is, however, makrûh. (Âlamgiri)
One can make I’tikaf in one masjid and lead tarawîh in another provided when sitting for I’tikaf this intention was made. (Âlamqiri vol. 1, p. 199)
TRANSFER OF MASJID
It is necessary for every person performing I’tikaf to complete his I’tikaf in the masjid where he commenced it. However, if he is faced with such an extreme difficulty and hardship that it is not possible for him to complete the I’tikaf in such a masjid, for example, because such a masjid may collapse, or he is removed therefrom under compulsion, or there is a strong danger to life or property by staying there (in the masjid), then it is permissible to move to another masjid and complete the I’tikaf there. If one has left for this purpose, the ’ltikaf will not be rendered void, provided that upon leaving one does not wait or remain on the road but proceeds directly to the other masjid. (Âlamgiri)
JANAZAH SALÂH AND VISITING THE SICK
(a) Generally it is not permissible for the person performing I’tikaf to leave the masjid to participate in Janazah Salâh or to visit the sick. However, if one left to attend the call of nature, and incidentally, on the road enquired of some person’s health or participated in a Janazah Salâh, then theI’tikaf is not rendered void. (Badai)
Moreover, one can visit or enquire of the sick whilst one is walking on. Consequently, Hadrat ’Aishah (R.A.) has said that the RasulullaSallallâhu ‘alayhi wasallam enquired of the sick whilst walking on, and he did not change his way for the purpose. (Abû Dawûd). In regard to Janazah Salâh it is a condition that one does not stop at all after the Salâh itself. (Mirqat).
(b) Apart from this, if a person makes a condition at the time of the intention of the I’tikaf itself to the effect that if he wishes during the course
of the I’tikaf to visit a certain sick person, or participate in Janazah Salâh, or attend a certain Islâmic or religious gathering, he will do so, then in such a situation it is permissible to leave the masjid for these purposes, and his I’tikaf will not thereby be rendered void. However, in this manner, his I’tikaf will become a nafl one, and will not remain Masnun.
FACTORS THAT RENDER I’tikaf VOID
I’tikaf is rendered void by the following factors:
1.   Apart from the necessities mentioned above, I’tikaf is rendered void if the person performing I’tikaf leaves the hudud of the masjidfor any other purpose although such leaving is for one moment (Hidâyah). It is clear that one will be said to have left the masjid when the feet (of the person performing I’tikaf) have been put outside in such a manner that according to custom one will be said to have left the masjid. Hence, if only the head is outside the masjid, then I’tikaf shall not thereby be rendered void. (Al?Bahr?ur?Raiq).
2.   Similarly, if a person performing I’tikaf leaves for a valid Shar’î necessity, but after completing such a necessity, he waits or stays outside (the masjid) even for one moment, then theI’tikaf is thereby rendered void. (Shâmi)
3.   If one leaves the masjid without a valid Shar’î reason or need, whether intentionally, in forgetfulness or by mistake, then in such situations the I’tikaf is rendered void. However, one will not sin for rendering the I’tikaf void if the leaving is due to mistake or forgetfulness. (ibid.)
4.   The I’tikaf will also be rendered void if a person under mistaken belief enters a part of the area of the masjid thinking that it falls within the hudud of the masjid, whereas in fact it is excluded there from. Hence, one must properly ascertain the hudud of the masjidbefore commencing I’tikaf.
5.   Since fasting is a condition for I’tikaf, if the fast breaks then I’tikafis rendered void accordingly, irrespective whether such fast was broken for a valid reason or not, or intentionally or by mistake. In each of these cases, I’tikaf is rendered void. The meaning of breaking fast by mistake is that a person whilst remembering that he is fasting does some involuntary act which is opposed to the requirement of fasting; for example, the person continued eating until the rise of dawn, or made Iftar before the setting of the sun under the mistaken belief taht the time for Iftar had passed; or whilst gargling water entered the gullet by mistake althought the person remembered that he was fasting. In all these situations, the fast is broken and I’tikaf is correspondingly rendered void.
However, if a person forgot that he was fasting and in such state of forgetfulness ate, and drank something, then both his fast andI’tikaf are not rendered void. (Shâmi)
6.   I’tikaf is also rendered void by sexual intercourse whether done inten­tionally or by mistake, and whether done during the day or night, inside the masjid or outside, and whether emission results or not. In all these situa­tions, I’tikaf is rendered void.
7.   Kissing and cuddling is not permissible during the course of I’tikaf if this causes emission, then I’tikaf is rendered void. However, if no emision results then notwithstanding its illegality, the ’ltikaf is not rendered void. (Hidâyah)
SITUATIONS IN WHICH IT IS PERMISSIBLE TO BREAK I’tikaf
It is permissible to break I’tikaf in the following situations:
1.   If such a disease emerges during the course of I’tikaf which is not possible to cure except by leaving the masjid, then it is permissible to break the I’tikaf.
2.   It is permissible to break I’tikaf and go outside (the masjid) in order to save a person who is drowning or burning or to prevent a fire. (Shâmi)
3.   It is permissible to break I’tikaf because of extreme disease which has afflicted one’s parents, wife or children.
4.   It is permissible to break I’tikaf if one is compelled to go outside (the masjid), for example, if a warrant of arrest is issued by the government.
5.   If a janazah arrives and there is nobody else to perform the Janazah Salâh, then also it is permissible to break the I’tikaf. (Fath?ul?Qadir)
THE CONSEQUENCES OF BREAKING I’tikaf: RULES OF QADHA
1.   If the I’tikaf Masnûn is rendered void for any of the reasons set forth above, then it is wâjib to make qadah only of that day in which the ’ltikaf’ was rendered void. It is not wâjib to make qadah of the full ten days. (Shâmi). The procedure of making qadha of this one day is as follows:
If there is time remaining in that Ramadhân, then one must perform I’tikaf with the niyâh of qadha in that Ramadhân commencing from the setting of the sun of one day until the setting of the sun of the following day. If there is not time in that particular Ramadhân or if it is not possible for any reason to perform I’tikaf therein, then apart from Ramadhân, one can keep fast on any day and perform I’tikaffor one day. On the other hand, if one makes qadah the following Ramadhân this also will be valid. However, there is no guarantee of life and accordingly one must make qadah as quickly as possible.
2.   If the I’tikaf Masnun is rendered void, it is not necessary to leave the masjid. But one can continue the I’tikaf for the remainder of the last ten days with niyyah of nafl. In this way, the sunnah al?Mu’akkadah will not be fulfilled but thawab will be obtained for the naflI’tikaf. On the other hand, if the I’tikaf was rendered void due to some involuntary mistake, then it is not inconceivable that Allâh Ta’âlamay bestow in His infinite mercy the reward of the Masnun I’tikaf of the last ten days. Hence, it is preferable in the case of the breaking of the I’tikaf is broken and to commence a permissible to leave on the day that I’tikaf is broken and to commence a nafl I’tikafwith nafl niyyah the following day.
THE ADAB OF I’TIKAF
In view of the fact that the purpose of I’tikaf it to withdraw oneself from worldly affairs and devote oneself entirely to the remembrance of Allâh, therefore, one must during the course ofI’tikaf avoid unnecessary talk and work. Whatever time one finds, one must spend in performing qadha salâhnawafil (Salâh), tilawah al?Qur’ân, and other ‘ibâdahdhikr and tasbihat. Moreover, the learning and teaching of ‘ilm of dîn, lectures and nasiliat and study of Islâmic books is not only permissible but also a cause of obtaining thawab.
PERMISSIBLE ACTS [MUBAHAT] IN I’TIKAF
The following acts are permissible in the state of I’tikaf
1.   Eating and drinking.
2.   Necessary transactions of purchase and sale relating to the necessities of life. However, it is not permissible to make the masjid a centre of trade as such. (Qazi Khan)
3.   Sleeping.
4.   Haircut provided the hair does not fall in the masjid.
5.   Talking and conversation, but it is necessary to avoid unnecessary talk. (Shâmi)
6.   To contract a Nikâh or other transactions. (al?Bahr)
7.   To change clothes, apply scent and oil. (Kulasatul Fatâwa)
8.   To assist a sick person in the masjid, apply bandage or show him a medicine. (Fatâwa Darul Uloom)
9.   To give lessons on the Qur’an or ’ilm of Din. (Shâmi)
10.  To wash and sew clothes provided that when washing the person remains within the masjid and the water falls outside the masjid. This ruling also applies in the case of washing pots or utensils.
11.  To pass wind in the masjid at the time of necessity. (Shâmi)
Moreover, all those actions are permissible in I’tikaf which are not makrûh or render I’tikaf void, and which actions in themselves arehalâl.
MAKRUHAT OF I’tikaf
The following matters are makrûh in the state of I’tikaf:
1.   To adopt complete silence because the adoption of complete silence in the Sharî’ah does not constitute I’tikaf. If one adopts silence with the intention that such silence is I’tikaf, then he will receive the sin of bid’ah. However, there is no objection if one does not regard silence as ibâdah and endeavours to remain silent in order to avoid sin. However, whenever a necessity arises, one must not avoid or abstain from talk. (Durre?Mukhtâr)
2.   To indulge in unnecessary and vain talk; some conversation is permissi­ble in accordance with necessity, but it is obligatory to avoid making the masjid a place of vanities and unnecessary talk. (Minhatul Kaliq)
3.   To bring goods of trade and throw them in the masjid.
4.   To enclose such area of the masjid for the purpose of I’tikaf that other persons performing I’tikaf or Salâh are caused difficulty or hardship.
5.   To charge a fee for writing, or sewing clothes, or teaching on the part of the person performing I’tikaf has been considered asmakrûh by the jurists (Al?Bahr). However, if a person cannot earn to provide for himself for the fasts of the days of I’tikaf without charging such fee, then it is permissible for him to do so on the analogy of sale. (And Allâh knows best).
6.   While performing the sunnah to indulge in a makrûh is not correct.
I’tikaf MANDHUR
The second type of I’tikaf is I’tikaf Mandhur”, that is, that I’tikaf which a person has made obligatory upon himself by taking a vow [nadhr].
Having regard to the fact that this particular form of I’tikaf is rare in occurrence, only the necessary rules have been set out below. For details, one should refer to the books or jurisprudence or a Mufti.
CATEGORIES OF NADHR AND THEIR LEGAL EFFECT
There are two categories of Nadhr:

(i) Nadlir Mu’ayyan, and

(ii) Nadhr Ghayr Mu’ayyan.

(i)   Nadbr Muayyan: this means that the Niyyah of I’tikaf is made for specific day or days or month; for example, a person makes Nadhr that he will perform I’tikaf in the last ten days of Sha’ban. However, if for some reason he cannot keep fasts in these days, then he must make qadah in other days. (Shâmi)
(ii) Nadhr Ghayr Muayyan: this means that no specific month or day is fixed for the performance of I’tikaf; for example, a person makes Nadhr that he will perform I’tikaf for three days. Hence, it will be permissible for him to performI’tikaf in all those days in which it is valid to keep fasts, and accordingly, his Nadhr will be fulfilled if he performs I’tikaf in such days.
NAFL I’TIKAF
1.   The third type ofI’tikaf is Nafl I’tikaf. This form of I’tikaf is not subject to time, fasting, day, night ? on the contrary, g person will receive the reward of I’tikaf if he enters the masjid with the intention of I’tikaf at any time and for whatever period.
2.   In the last ten days of Ramadhân, if a person performs I’tikaf with the requisite intention for less than ten days, then such I’tikafwill be Nafl I’tikaf.
3.   If a person goes to the masjid for the purpose of Salâh and at the time of entering (the masjid) formulates an intention to the effect that he will remain in I’tikaf for whatever time he spends in he masjid, then such person will receive the reward of I’tikaf.
4.   Nafl I’tikaf remains in force for the period that the person is in the masjid. Upon leaving or emerging from the masjid, thisI’tikaf ends.
5.   The person performing Nafl I’tikaf should complete I’tikaf for the period or days that he intended to undergo in I’tikaf.
6.   However, if he leaves the masjid for some reason prior to completion of the intended period, then he will receive reward for the period he remained in the masjid. For the remaining (that is, uncompleted) period, he is not obliged (that is, it is not wâjib upon him) to make qadah. (Shâmi).
7.   If a person, for example, made intention to perform I’tikaf for three days and thereafter upon entering the masjid, he commits an act which breaks his I’tikaf, then in such event his I’tikaf is completed, that is, he will receive the reward for the period he spent in themasjid prior to breaking of his I’tikaf, and furthermore, no qada’ is wâjib upon him (for the uncom­pleted period). In this event, he may leave the masjid if he wishes, or remain therein by making a new intention of I’tikaf. In such a situation, it is preferable that he completes the period for which he had made the intention of I’tikaf.
I’tikaf OF WOMEN
1.   The fadilah of I’tikaf is not confined to men; women also can take advantage of it. However, women should not perform I’tikaf in the masjid. Their I’tikaf is only possible in the house. The procedure is as follows:
Women should sit for I’tikaf in that place in the house which has been set aside for Salâh and ‘Ibadah. If no such place has been previously set aside, then a place must be so set aside prior to the commencement of I’tikaf, and I’tikaf must accordingly be performed therein. (Shâmi)
2.   If no specific place has been built or set aside in the house for Salâh, and it is not possible for some reason to so build or set aside a place therein, then in such event a woman may at her discretion demarcate any place within the house and perform I’tikaf there. (Âlamghiri)
3.   It is necessary for a married woman to obtain the consent of her husband for the purpose of performing I’tikaf. It is not permissible for a woman to perform I’tikaf without the permission of her husband. (Shâmi) However, husbands should not without reason deprive their wives of performing I’tikaf by refusing consent. On the contrary, they should grant consent.
4.   If a woman has commenced I’tikaf with the permission of her husband and thereafter he endeavours to prohibit or prevent her from completing same, then he cannot do so. If he succeeds in preventing her, then the woman is not obliged to completeI’tikaf. (Alamghiri)
5.   It is necessary for a woman to be free from menstruation and Nifâs in order to perform I’tikaf ? that is, she cannot perform I’tikafin a stage of menstruation and Nifâs.
6.   Consequently, a woman should, prior to the commencement of Masnun I’tikaf, determine whether the date of her menstruation will coincide with the period of I’tikaf. If the menstruation is expected to occur towards the end of the last ten days of Ramadhân, then she must not perform Masnun I’tikaf. However, she may perform Nafl I’tikaf for the period until the arrival of her menstruation.
7.   If a woman has commenced I’tikaf, and thereafter menstruation com­mences during the duration of I’tikaf, then it is wâjib upon her to imme­diately abandon I’tikaf, as soon as her menstruation commences. In such a situation it is wâjib upon her to make qada I’tikaf of only the day in which she abandoned the I’tikaf (as a result of the intervention of menstruation). The procedure of such qadah is as follows:
After the woman becomes pure of such menstruation, she keeps fast on any day and performs I’tikaf. If the days remain in Ramadhân, then she may make qadha in Ramadhân in which case the fast of Ramadhân will be sufficient. However, if Ramadhân has terminated at the time of her becom­ing pure from such menstruation, then she must thereafter specifically keep fast qadha I’tikaf for one day. (Commentary to Behesti Zewar)
8.   The place within the home demarcated by a woman for the purpose of I’tikaf will for the duration thereof fall within the hukm of the masjid. It is not permissible for her to move from such place without a Shar’î necessity. She cannot leave such place and enter any other portion or area of the home. If she does so, her I’tikaf will break.
9.   The rules applicable to men relating to moving from the place of I’tikaf are also applicable to women. For those needs and necessities in relation to which it is permissible for men to leave the masjid, it is similarly permissi­ble for women to leave the place of I’tikaf for such needs and necessities. (not Janazah). For those works in relation to which it is permissible for men to leave themasjid, it is similarly permissible for women to leave the place of I’tikaf for such works. Accordingly, women should, prior to commencing I’tikaf, thoroughly acquaint themselves with the rules relating to I’tikaf Masnun which have been discussed earlier under the heading “I’tikaf Masnun”.
10.  During the I’tikaf, women may, whilst sitting in their place of I’tikaf indulge in sewing and knitting. They can advise and guide others in regard to matters affecting the home. However, they cannot leave the place demarcated for I’tikaf. Moreover, it is preferable if they concentrate during the I’tikaf on DhikrTasbihatTilawat al?Qur’an and ‘Ibadat. They should not spend too much time on other matters.
