Abdullah bin Umar reported,

He informed him that he had divorced his wife while she was menstruating. Umar mentioned this to the Prophet ﷺ, and the Messenger of Allah ﷺ became angry with him. He then said, "Let him take her back and keep her until she becomes pure, then menstruates, then becomes pure again. After that, if he still wishes to divorce her, let him divorce her."
