Sahih Muslim, 3580

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 (ﷺ) and I made a mention of it to him, and he said: He can enter (your house), for he is your uncle

Rapporté par Aïcha رضي الله عنها : Aflah ibn Qu’ais m’a demandé la permission d’entrer, mais je la lui ai refusée. Il m’a envoyé un message disant : « Je suis ton oncle, car la femme de mon frère t’a allaitée. » Mais j’ai continué à lui refuser la permission. Le Messager d’Allah ﷺ est arrivé et je lui en ai parlé. Il a dit : « Il peut entrer, car c’est ton oncle. »
