because the Prophet, may Allah bless him and grant him peace, commanded Ibn Umar to take her back. Had the divorce not taken effect, he would not have commanded him to take her back. If he takes her back while she is menstruating, he may divorce her during the period of purity following that menstruation, before having intercourse with her, as Yunus ibn Jubayr and Anas ibn Sirin narrated from Ibn Umar.
As for what Nafi narrated from Ibn Umar—“Then let him keep her until she becomes pure, then menstruates, and then becomes pure”—this indicates recommendation. It is recommended that he delay the divorce until the second period of purity, so that his taking her back is not merely for the purpose of divorcing her, just as it is disliked to enter into marriage merely in order to divorce.
According to some scholars, there is no departure from the Sunnah in combining the three pronouncements of divorce. Thus, if a man divorces his wife three times during a state of purity, he is not considered to have carried out an innovated divorce. This is the view of al-Shafi‘i and Ahmad. Others held that it is an innovated form of divorce; this is the view of Malik and the scholars of legal reasoning.
His saying, exalted is He: “And carefully reckon the waiting period”—that is, preserve the count of her menstrual cycles. It is said that He commanded the waiting period to be counted so that, if he wishes to pronounce three divorces, he may distribute them over the menstrual cycles. It is also said that this is in order to know how much time remains for taking her back and to observe the rulings concerning maintenance and housing.
“And fear Allah, your Lord. Do not turn them out of their homes”: this refers to when the dwelling in which he divorced her belongs to the husband; it is not permissible for him to turn her out of it. “Nor should they leave”: nor is it permissible for her to leave until her waiting period has ended. If she leaves without necessity or a legitimate need, she sins. But if a necessity arises—for example, if she fears that the building will collapse or that it will be flooded—she may move to another residence. Likewise, if she has some need, such as selling yarn or buying cotton, she may go out during the day, but not at night. For some men were martyred at Uhud, and their wives said, “We feel lonely in our homes.” So the Prophet, may Allah bless him and grant him peace, permitted them to converse at one another’s homes; but when it was time to sleep, each woman was to return to her own home. (1) The Prophet, may Allah bless him and grant him peace, also permitted Jabir’s maternal aunt, whose husband had divorced her, to go out to harvest the dates from her palm trees. (2)
If her waiting period becomes due while she is travelling, she observes it while continuing her journey and returning. A Bedouin woman takes up lodging wherever her people take up lodging during her waiting period, (3) because moving about is, in their case, like residence is for one who is settled.
His saying: “Unless they commit a clear indecency”: Ibn Abbas said: “The clear indecency” is for her to behave obscenely toward the members of
