It was narrated from Zubair bin 'Awwam that he was married to Umm Kulthum bint 'Uqbah, and she said to him when she was pregnant: "I will accept one divorce." So he divorced her once. Then he went out for prayer, and when he came back she had given birth. He said: "What is wrong with her? She misled me, may Allah mislead her!" Then he came to the Prophet P.B.U.H who said: "Her waiting period is over (and she is divorced); propose marriage anew to her." (Da'if)
