Musannaf Ibn Abi Shaybah 22954 — Selling umm walad slave women

It is narrated from Nafi' that two men from the people of Iraq asked Sayyiduna Ibn Umar (may Allah be pleased with them both) at al-Abwa'. They said: We left Sayyiduna Ibn al-Zubayr (may Allah be pleased with him) in Makkah selling umm walad women. Sayyiduna Ibn Umar (may Allah be pleased with them both) said: But do you know Sayyiduna Umar (may Allah be pleased with him)? He (may Allah be pleased with him) said: Any man whose slave woman becomes pregnant by him and bears a child, she is a source of benefit for him during his lifetime, and after his death that slave woman is free. And any man who has intercourse with a slave woman and then neglects her, the child is his and the consequence of that neglect is upon him.
