Section

If he says, “If you menstruate, then you are divorced,” she is divorced at the onset of the first menstruation that is certainly established. If he says, “If you menstruate one full menstrual period,” she is divorced at the beginning of purity following a complete menstrual period. And if he says, “If you menstruate half a menstrual period,” she is divorced halfway through her customary menstrual duration.

In this section, the author discusses making divorce contingent upon menstruation—its beginning, its end, and partway through it. When our Shaykh (1), may Allah have mercy on him, reached this passage, he would skip over it, saying: “They are all merely examples.” Yet we read it, since an important issue may occasionally arise.

His statement, “If he says: ‘If you menstruate, then you are divorced,’ she is divorced at the onset of the first menstruation that is certainly established”: although this divorce is prohibited and an innovated form of divorce, the established school holds that an innovated divorce takes effect. It has previously been mentioned that the correct view is that it does not take effect.

His statement, “If you menstruate one full menstrual period, she is divorced at the beginning of purity following a complete menstrual period”: this is clear, because he said, “If you menstruate one menstrual period.”

His statement, “And if he says: ‘If you menstruate half a menstrual period,’ she is divorced halfway through her customary menstrual duration” (2).
