Musannaf Ibn Abi Shayba 9:1675

'Abdah narrated to us, from 'Asim, who said: A woman came to Abu Musa, and her father, her husband, and her mother [were with her], and she was pregnant. Her husband was saying, "She is a slave girl, and I was only playing with her." So he spoke to the girl, and she said, "My father and my mother married me off to him, and he used to enter upon me and do with me what a man does with his wife." He said: So he struck his head with the whip and said, "She is your wife, and the child is your child."
