If he divorces her once in each period of purity: when does her waiting period end?

Sayyiduna Abdullah (may Allah be pleased with him) said: If a man wishes to divorce his wife three times according to the Sunnah, he should give her one divorce in each period of purity, and after the last divorce she observes the waiting period (iddah) with one more menstruation.

Ibrahim (may Allah have mercy on him) said: After the last divorce, the waiting period of one more menstruation will be binding on the woman.

Abu Qilabah (may Allah have mercy on him) considered it disliked (makruh) to divorce a woman at every menstruation; according to him, this practice lengthens the woman's waiting period. In that case, in his view, the waiting period is counted from the first divorce, provided he has not taken her back in between.

Al-Hasan (may Allah have mercy on him) used to say: If a man divorces his wife and then, a month later, gives her a second divorce, her waiting period runs from the first divorce, as long as he has not taken her back.

Sa'id bin al-Musayyib (may Allah have mercy on him) said: If a man gives his wife one divorce at each menstruation, the waiting period is counted from the first divorce, provided he has not taken her back.

Ibrahim (may Allah have mercy on him) and Khaythamah (may Allah have mercy on him) said: Each time she menstruates, one divorce takes effect, and after the three she observes one more menstruation as her waiting period.

Waki' (may Allah have mercy on him) said: People act according to this.

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) and Khilas bin Amr (may Allah have mercy on him) said: She will begin her waiting period from the last divorce.

Sa'id bin al-Musayyib (may Allah have mercy on him) said: We do not approve of that.
