Ibn Tawus narrated from his father that he heard 'Abdullah bin 'Umar being asked about a man who divorced his wife when she was menstruating. He said:
Do you know 'Abdullah bin 'Umar? He said: Yes. He said: He divorced his wife when she was menstruating, and 'Umar went to the Prophet and told him about that. He ordered him to take her back until she became pure, and I did not hear him adding anything to that.
