It is narrated from Sayyiduna Uqbah bin al-Harith (may Allah be pleased with him) that he married Umm Yahya bint Abi Ihab. Then a black slave woman came and said: I breastfed both of you. Sayyiduna Uqbah bin al-Harith (may Allah be pleased with him) said: I came to the Prophet (peace and blessings be upon him) and mentioned it to him, but he turned away. I mentioned it to him again, and he (peace and blessings be upon him) said: "How can it be, when she has claimed that she breastfed both of you?" And he forbade him from her (that wife).
