It is narrated from Umm Mubashshir (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) proposed marriage to the wife of Sayyiduna al-Bara' bin Ma'rur (may Allah be pleased with him). She said: I made a condition with my husband that I would not marry after him. So the Prophet (peace and blessings be upon him) said: "This is not right."
