Sayyiduna Uqbah bin al-Harith (may Allah be pleased with him) said: I married the daughter of Abu Ihab al-Taymi. On the morning after the marriage, a freed slave woman of my family in Makkah came and said: I breastfed both of you. So I rode to the Prophet (peace and blessings be upon him), who was in Madinah at the time. I mentioned it to him and said: I asked the girl's family and they denied it. He (peace and blessings be upon him) said: "How can it be, when it has already been said?" Sayyiduna Uqbah (may Allah be pleased with him) said: So I separated from her and married someone else.
