Musannaf Ibn Abi Shaybah

A person from among the descendants of Hazrat Rafi’ bin Khadij (may Allah be pleased with him) narrates that Hazrat Rafi’ bin Khadij (may Allah be pleased with him) married his daughter to the son of his brother, Rafa’ah bin Khadij, even though the girl had been breastfed by a woman who was not the boy’s mother, but was a slave woman of Hazrat Rafa’ah bin Khadij (may Allah be pleased with him), from whom he also had children. That is, the reason for the milk of that slave woman was Hazrat Rafa’ah (may Allah be pleased with him).
