Sayyiduna Uqbah bin al-Harith (may Allah be pleased with him) said: I married Umm Yahya bint Abi Ihab. Then a black woman came to us and claimed that she had breastfed both of them. I mentioned it to the Prophet (peace and blessings be upon him), and he turned away from me. I mentioned it again to the Prophet (peace and blessings be upon him), and again he turned away. I mentioned it to him once more, and again he turned away. I said: She is lying. He (peace and blessings be upon him) said: "How do you know that she is lying, when she has said what she said? Separate her (your wife) from yourself."
