Baqiyya bin al-Walid bin Sa'aid بقية بن الوليد بن صائد · The Book of Divorce

"I asked Ibn 'Umar about a man who divorced his wife while she was menstruating. He said: 'Do you know 'Abdullah bin 'Umar?' He divorced his wife while she was menstruating, and 'Umar asked the Prophet about that, and he told him to take her back, then wait for the right time. I said to him: 'Was that divorce counted?' He said: 'Be quiet! What do you think if some becomes helpless and behaves foolishly?'"
