A'isha (Allah be pleased with her) reported that Salim, the freed slave of Abu Hadhaifa, lived with him and his family in their house. She (i. e. the daughter of Suhail came to Allah's Apostle (ﷺ) and said:Salim has attained (purbety) as men attain, and he understands what they understand, and he enters our house freely, I, however, perceive that something (rankles) in the heart of Abu Hudhaifa, whereupon Allah's Apostle (ﷺ) said to her: Suckle him and you would become unlawful for him, and (the rankling) which Abu Hudhaifa feels in his heart will disappear. She returned and said: So I suckled him, and what (was there) in the heart of Abu Hudhaifa disappeared
