If he abstains from intercourse with her in order to harm her, without an oath and without excuse, then he is like one who has sworn abstinence (mūlī).
His words, “If he abstains from intercourse with her in order to harm her, without an oath and without excuse, then he is like one who has sworn abstinence,” mean that he is treated as one who has sworn abstinence. This is like a man who abstains from intercourse with his wife without taking an oath, but does so in order to harm her. He is sinful; therefore, we give him the same ruling as one who has sworn abstinence. According to the author’s wording, he is given four months from the time he began abstaining, on condition that his intention is to harm her. We say to him: either have intercourse with her and live with her honorably, or, if she seeks annulment, the marriage is dissolved.
It was also said that he is not like one who has sworn abstinence, and that we cannot give him the same ruling when the actual circumstances differ. This is the sounder view: one who abstains from intercourse with her in order to harm her, without an oath and without excuse, is not one who has sworn abstinence. Rather, he must be required to live with her honorably; otherwise, she is entitled to seek annulment or divorce. The difference between him and one who has sworn abstinence is that the latter has taken an oath, and the waiting period mentioned by Allah follows from his oath, out of consideration for it. As for this man, he is merely harming her. The Messenger of Allah ﷺ said: “There should be neither harm nor reciprocating harm” (1). Allah the Exalted also says: “Do not keep them, intending harm, to transgress against them.” [al-Baqarah 2:231] How, then, can we say that such harm is to last four months?!
Thus, the correct view in this matter is that it should be said: whoever abstains from intercourse with her in order to harm her,
