Ibn Sirin محمد بن سيرين الأنصاري · The Book of Marriage

"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."

It was narrated from Anas that the Messenger of Allah manumitted Safiyyah and made her freedom her dowry.
