Musnad Ahmad 5792

Translation

✧ I divorced my wife during the time of the Messenger of Allah ﷺ while she was menstruating. Umar mentioned that to the Messenger of Allah ﷺ, and he said: Command him to take her back until she becomes pure, then has another period. When she becomes pure, he may divorce her if he wishes before having intercourse with her, or keep her, for that is the waiting period at which Allah has commanded women to be divorced.
