Marriage
Book Number: 005 / Hadith Number: 2052
Narated By 'Aisha, Ummul Mu'minin : Aflah ibn AbulQu'ays entered upon me. I hid myself from him. He said: You are hiding yourself from me while I am your paternal uncle. She said: I said: From where? He said: The wife of my brother suckled you. She said: The woman suckled me and not the man. Thereafter the Apostle of Allah (pbuh) entered upon me and I told him this matter. He said: He is your paternal uncle; he may enter upon you.
