Bishr bin Sa'id narrates that Khawat bin Jubair reported: A man made a bequest to him; that man left behind among his heirs an umm walad and a free wife. There arose a dispute between the woman and the umm walad, so the free woman sent a message to the umm walad: "You will soon be sold, O worthless girl." Sayyiduna Khawat bin Jubair (may Allah be pleased with him) presented this matter before the Prophet Muhammad (peace and blessings be upon him), so he (peace be upon him) said: "She cannot be sold." By the order of the Prophet Muhammad (peace and blessings be upon him), she was declared free.
