The Book of Marriage (Kitab Al-Nikah)

Muslim :: Book 8 : Hadith 3406

'A'isha (Allah be pleased with her) reported: Aflah b. Qu'ais sought permission from me (to enter the house), but I refused to grant him the permission, and he sent me (the message saying): I am your uncle (in the sense) that the wife of my brother has suckled you, (but still) I refused to grant him permission. There came the Messenger of Allah (may peace be upon him) and I made a mention of it to him, and he said: He can enter (your house), for he is your uncle.
