Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates: During the time of the Prophet (peace and blessings of Allah be upon him) and Sayyiduna Abu Bakr (may Allah be pleased with him), we used to sell Umm Walad slave women. When the era of Sayyiduna Umar (may Allah be pleased with him) came, he forbade selling them.
