Mujahid (may Allah have mercy on him) said: A man of Quraysh gave his wife an irrevocable divorce (talaq battah). Then he passed by an old Bedouin man and his son in the market, who had come there for trade. He said to the young man: Is there any good in you? Then he went away from him, then came back to him and said the same, then went away again. He said: Yes. He said: Show me your hand. Then he went with him, told him the matter and instructed him to marry that woman. He married her and spent the night with her. When morning came, he asked permission (to leave) and was given permission; then suddenly he had turned his back on her. The woman said (to the first husband): If he divorces me now, I will never marry you. This was mentioned to Sayyiduna Umar (may Allah be pleased with him), so he summoned him and said: Had you married her, I would have done such and such to you, and he threatened him. And he summoned her husband and said: Hold on to her. In another place it adds that he said: If anyone approaches you with anything, inform me.
