Musannaf Ibn Abi Shayba 9:524

'Isa ibn Yunus narrated to us, from 'Umar ibn Sa'id ibn Abi Husayn, who said: 'Abdullah ibn Abi Mulaykah narrated to me, who said: 'Uqbah ibn al-Harith narrated to me, saying: I married the daughter of Abu Ihab al-Taymi. When it was the morning after the consummation of the marriage, a slave woman of the people of Mecca came and said: "I have suckled both of you." 'Uqbah rode to the Prophet, may Allah bless him and grant him peace, while he was in Medina, and mentioned that to him. I had asked the girl's family, and they denied it. He (the Prophet) said: "How [can you keep her] when it has been said?" So he separated from her, and she married someone else.
