Sadaqah bin Abdullah al-Dimashqi (may Allah have mercy on him) said: I came to Muhammad bin al-Munkadir (may Allah have mercy on him) in a state of anger and said: "By Allah! You have declared Umm Salamah lawful for al-Walid bin Yazid." He said: "Not I, but the Messenger of Allah (peace and blessings be upon him)." Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) heard the Messenger of Allah (peace and blessings be upon him) say: "A woman who is not your wife cannot be divorced, and a slave whom you do not own you cannot free."
