"The Messenger of Allah commanded the wife of Abu Hudhaifah to breast-feed Salim, the freed slave of Abu Hudhaifah, so that the protective jealousy of Abu Hudhaifah would be dispelled. She breast-fed him when he was a man." (One of the narrators) Rabi'ah said: "That was a concession granted to Salim."

← Previous Hadith "Sahlah bint Suhail came to the Messenger of Allah and said: 'I see (displeasure) in the face of Abu Hudhaifah when Salim enters upon me.' The Messenger of Allah said: 'Breast-feed him.' She said: 'How can I breast-feed him when he is a grown man?' He said: 'Don't I know that he is a grown man?' Then she came after that and said: 'By the One Who sent you with the truth as a Prophet, I have never seen anything I dislike on the face of Abu Hudhaifah after that.'"

He said: 'Breast-feed him, and you will become unlawful to him thereby.' (Ibn Abi Mulaikah, one of the narrators said:) For a year I did not narrate this, then I met Al-Qasim and he said: 'Narrate it and do not worry about it.'"
