It is narrated from Sayyiduna Uqbah bin al-Harith (may Allah be pleased with him) that Umm Yahya was married to him. Then a black woman came and said: I breastfed both of you. So he came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! A black woman has claimed that she breastfed me and my wife, though she is lying. He (peace and blessings be upon him) turned away. Then he said it to him again, and the Prophet (peace and blessings be upon him) said: "Then leave her."
