Musnad Ahmad 5299

Translation

✧ He divorced his wife while she was menstruating. ʿUmar asked the Prophet ﷺ, and he said: "Command him to take her back, then keep her until she becomes pure, then menstruates, then becomes pure. Then if he wishes, he may divorce her, and if he wishes, he may keep her. That is the waiting period in which God has commanded women to be divorced."
