Sahih Al Bukhari (632)

أخبرني عبد الله بن أبي مليكة عن عقبة بن الحارث "أنه تزوج ابنة لأبي إهاب بن عزيز فأتته امرأة فقالت قد أرضعت عقبة والتي تزوج فقال لها عقبة ما أعلم أنك أرضعتني ولا أخبرتني فأرسل إلى آل أبي إهاب يسألهم فقالوا ما علمنا أرضعت صاحبتنا فركب إلى النبي (صلى الله عليه وسلم) بالمدينة فسأله فقال رسول الله (صلى الله عليه وسلم) كيف وقد قيل ففارقها ونكحت زوجا غيره"

`Abdullah ibn Abu Mulaykah reported from `Uqbah ibn Al Harith: `Uqbah married the daughter of Abu Ihab ibn `Aziz, and then a woman came and said: "I suckled `Uqbah and his wife." `Uqbah said to her: "I do not know that you have suckled me, and you did not inform me." He then sent someone to the house of Abu Ihab to enquire about that but they did not know that she had suckled their daughter. Then `Uqbah went to the Prophet (peace be upon him) in Medina and asked him about it. The Prophet (peace be upon him) said to him: "How (can you keep your wife) after it has been said (that both of you were suckled by the same woman)?" So, he divorced her and she was married to another (husband).
