Chapter: Breastfeeding is because of Hunger (meaning, during infancy)

Allah's Messenger (ﷺ) visited me when a man was sitting near me, and he seemed to disapprove of that. And I saw signs of anger on his face and I said: Messenger of Allah, he is my brother by forsterage, whereupon he said: Consider who your brothers are because of fosterage since fosterage is through hunger (i. e. in infancy).

This hadith is narrated on the authority of Abu al-Ahwas with another chain of transmitters and a slight variation of words.
