"Tell him to take her back, then divorce her while she is pure (not menstruating) or pregnant."
Sunan an-Nasa'i Book 27, Hadith 9
← Previous Hadith "Tell 'Abdullah to take her back, then, when she has performed Ghusl, let him leave her alone, until she menstruates (again). Then, when she performs Ghusl following that second period, he should not touch her until he divorces her. And if he wants to keep her, then let him keep her. That is the time when Allah has stated that women may be divorced."

Sunan an-Nasa'i Book 27, Hadith 8 Next Hadith → It was narrated from Ibn 'Umar that he divorced his wife when she was menstruating, but the Messenger of Allah told him to take her back, and divorce her when she was pure (not menstruating).
