Chapter 18: The Book of Suckling
' A' isha (Allah be pleased with her) reported: My foster uncle came to me and sought permission (to enter the house), but I refused him permission until I had solicited the opinion of Allah' s Messenger (ﷺ). When Allah' s Messenger (ﷺ) came, I said to him: My foster-uncle sought my permission to (enter the house), but I did not permit him, whereupon Allah' s Messenger (ﷺ) said: You better admit your uncle (into the house). I (' A' isha) said: It was the woman who suckled me and not the man. (But he) said: He is your uncle, admit him.
