(76) باب الرَّجْعَةِ
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.
