Narrated by Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): The Noble Prophet (peace and blessings be upon him) said: Any slave woman who gives birth to a child by her master will become free after the death of that master.

It is narrated from Sayyiduna Jabir (may Allah be pleased with him), he says: We used to sell our captives and ummahat al-awlad while the Noble Prophet (peace and blessings be upon him) was still alive among us, and he (peace and blessings be upon him) did not consider there to be any harm in it.

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him), he says: In the time of the Messenger of Allah (peace and blessings be upon him), we used to sell ummahat al-awlad (slave women who had borne children to their masters).

It is narrated from Sayyida Salama bint Ma’qil (may Allah be pleased with her), she says: I was the slave woman of Sayyiduna Hubab bin Amr (may Allah be pleased with him), and a child was also born to him from me. (But when he passed away,) his wife said to me: Now you will be sold to pay off his debt. So I went to the Messenger of Allah (peace and blessings be upon him) and informed him of this matter. The Messenger of Allah (peace and blessings be upon him) said: Who is the guardian of the inheritance of Hubab bin Amr? The people said: His brother, Sayyiduna Abu al-Yasar Ka’b bin Amr (may Allah be pleased with him). The Messenger of Allah (peace and blessings be upon him) called him and said: You are not to sell her, rather you are to set her free. When you hear that slaves have come to me, come to me, and I will give you compensation for her. He did so, but after the death of the Messenger of Allah (peace and blessings be upon him), there was a difference of opinion regarding this issue. Some people were of the view that the umm walad (a slave woman who bore her master a child) remains a slave after her master’s death. If her ruling was not that of a slave, the Messenger of Allah (peace and blessings be upon him) would not have given them a slave in exchange for her. While others said that such a woman becomes free, because the Messenger of Allah (peace and blessings be upon him) set her free. Sayyida Salama (may Allah be pleased with her) says: There was a difference of opinion among the companions regarding me.
