Malik related to me from Nafi that Safiyya bint Abi Ubayd informed him that Umar ibn al-Khattab said, "What is the matter with men who have intercourse with their slave-girls and then leave them to go? No slave-girl comes to me whose master confesses that he has had intercourse with her but that I connect her child to him, whether or not he has practised coitus interruptus or left off from intercourse with her." Yahya said that he heard Malik say, "What is done in our community about an umm walad who commits a crime is that her master is liable for what she has done up to her value. He does not have to surrender her, and he cannot be made to bear more than her value for her crime."
