1760. Having started the i‘tikÁf, a person may decide to return from it and void it as long as two days have not elapsed, in the event that it is not a date-specific i‘tikÁf, such as one undertaken to fulfill a nadhr to perform i‘tikÁf on particular dates. However, if while forming his intention he stipulates that in the event that something comes up for him, he can choose to return from his i‘tikÁf, he may return from it even if two days have passed.

1761. A person who is engaged in i‘tikÁf must refrain from certain acts, committing which will void the i‘tikÁf. However, the obligation to refrain from them—other than intercourse—in an i‘tikÁf which is not a date-specific obligation, is based on obligatory precaution. These acts are:
1. Sexual intercourse, and obligatory precaution will dictate the same of masturbation, and coming in direct contact with a woman by touching or kissing her with desire.
2. Fragrant scents.
3. Buying or selling, which will invalidate the i‘tikÁf, but the transaction itself will not be invalidated. Obligatory precaution dictates that one should avoid all forms of transactions, even if it is in the form of a settlement, mudharabah or lease. Should a person be urgently compelled to buy or sell something, and be unable to appoint an agent, it will then be permissible.
4. Engaging in debates with the intention of overcoming the adversary and showing off one’s superiority, regardless of whether the debate pertains to a worldly matter, or a religious matter.

1762. If a person intentionally engages in sexual intercourse while performing i‘tikÁf, be it during the day or during the night, a kaffÁrah will become obligatory on him. The kaffÁrah in this case is that he either free a slave, or fast consecutively for two months, or feed sixty needy persons.
If a person commits any of the other acts that invalidate i‘tikÁf, other than intercourse, no kaffÁrah will be obligatory on him.

1763. If the person engaged in i‘tikÁf inadvertently commits one of the acts which invalidate i‘tikÁf, then to claim that it is still valid is problematic.

1764. If a person invalidates his i‘tikÁf by committing one of the aforementioned acts, in the event that it is an obligatory non-specific i‘tikÁf —such as a nadhr made to perform i‘tikÁf without specifying a particular time—then he will have to perform it again. In the event that it is an obligatory date-specific i‘tikÁf —such as a nadhr made to perform i‘tikÁf at a particular time—or a recommended i‘tikÁf, wherein the act is committed after the passage of two days, he will have to offer its qaÃÁ based on obligatory precaution. If he commits the act in a recommended i‘tikÁf prior to the passage of two days, he will not have to observe its qaÃÁ.

1765. Leaving one i‘tikÁf for another is not permissible, be they both obligatory—such as one obligated by a vow and another by swearing to perform it—or both recommended, or one obligatory and one recommended. It will also not matter if one is for oneself and the other is by proxy or being hired to perform i‘tikÁf, or both are being done by proxy.

1766. If a person engaged in i‘tikÁf sits on a usurped carpet, he will have committed a sin, but his i‘tikÁf will not be invalidated. However, if another person precedes him in acquiring the spot, and the one performing i‘tikÁf takes the spot without seeking the person’s consent, his i‘tikÁf in that spot will be invalid.

1767. If ghusl becomes obligatory on the person who is engaged in i‘tikÁf, he is not permitted to leave the mosque as long as he is not prohibited from performing ghusl in the mosque, such as the ghusl for touching a dead body. If he is, such as the ghusl of janÁbah which necessitates that a person remains inside the mosque in the state of janÁbah, he will have to leave the mosque. If he fails to do so, his i‘tikÁf will be rendered invalid.

1036. A person who performs rukÙ sitting, should bow to the degree that his face is positioned above his knees. The precaution is that one should bow to the degree that he would bow, were he to perform rukÙ standing.

1037. Unless a person is compelled, it is obligatory to recite either سُبْحانَ الله (Subhaan'Allah) ({^ glory be to Allah.^}) three times, or سُبْحانَ ربِّيَ العَظِيمِ وَ بِحَمْدِهِ (Subhaana rabbiyal 'adheeme wa bihamdeh) ({^glory be to Allah, the Supreme and Him do I praise.^}) once, or any dhikr that is equal to it in length. Recommended precaution dictates that the aforementioned tasbÐÎ should be given precedence over other dhikr, and when time is constricted or one is compelled, it is sufficient to recite سُبْحانَ اللَّه once.

1038. The words in the dhikr of rukÙ should be recited in close succession, correct Arabic, and it is recommended the dhikr be
سُبْحانَ ربِّيَ العَظِيمِ وَ بِحَمْدِهِ, recited three, five or seven times; rather, even more than seven times.

1768. It is obligatory to pay khums on the following seven things:
1. The profits from one’s earnings
2. Minerals
3. Treasure troves
4. Wealth which is an amalgamation of legal and illegal gains
5. Precious stones which are acquired by diving under the sea.
6. The spoils of war
7. The land which a dhimmÐ purchases from a Muslim
The precepts regarding these seven things have been elaborated in the following articles.

1039. One should maintain bodily composure during the obligatory dhikr of rukÙ. Obligatory precaution dictates that one should also maintain bodily composure during the recommended dhikr of rukÙ, if it is recited with the intention of the dhikr that is specified for rukÙ. However, if it is recited with the intention of dhikr in general, bodily composure is not necessary.

1040. If during the obligatory dhikr of rukÙ, a person involuntarily moves his body to the extent that he loses bodily composure, he should repeat the dhikr after regaining composure. However, if the movement of his body is so minute that it does not result in him losing composure, or he moves his fingers, there is no harm in it.

1041. If a person deliberately recites the dhikr of rukÙ prior to bowing the degree necessary for rukÙ, and prior to attaining bodily composure, his prayer is invalid, unless he is an excusable ignorant, in which case his prayer shall not be deemed invalid.

1042. If a person deliberately raises his head from rukÙ, prior to completing its obligatory dhikr, his prayer is invalid, unless he is excusable for his ignorance, in which case his prayer shall not be deemed invalid. A person who inadvertently raises his head from rukÙ, should recite the dhikr once he regains bodily composure, if he recollects prior to leaving the state of rukÙ. However, if he recollects after leaving the state of rukÙ, his prayer is valid.

1769. Whenever a person acquires wealth from commercial transactions, skilled trade or any other form of earning, even if it be the wages for performing the prayers or fasts of a deceased, then should it exceed his yearly expenses and that of his dependants (‘iyal) , he will have to pay its khums (one fifth of it) according to the instructions which will be elaborated in later articles.

1043. Whenever necessary, it is permissible for a person to limit the dhikr of rukÙ to one سُبْحانَ اللَّه and the recommended precaution is that he recites the other two while returning to the upright position.

1770. If a person acquires wealth without earning it, like acquiring a gift, which is of significant amount and value in the eyes of the people, and it exceeds his yearly expenses, he will have to pay its khums as well.

1044. If a person is unable to maintain bodily composure in rukÙ‘ due to an illness or something similar, his prayer is valid. He should however ensure that its obligatory dhikr is recited prior to leaving the state of rukÙ.
