Sa'id ibn al-Musayyib سعيد بن المسيب بن حزن أبو محمد القرشي · The Book on Divorce and Li'an

"I asked Ibn Umar about a man who divorced his wife while she was menstruating. So he said: 'Don't you know Abdullah bin Umar?' Indeed he divorced his wife while she was menstruating, so Umar asked the Prophet about that, and he ordered him to take her back.'" He said: "I said: And that divorce is counted? He said: And that divorce is counted? He said: 'What else would you think if he was helpless and foolish?'"

The Prophet said: "The women who seek a Khul are hypocrites."
