Yunus and Mansur narrated from Hasan al-Basri (may Allah have mercy on him) that when a woman testifies about a man and his wife that she has breastfed both of them, Hasan al-Basri (may Allah have mercy on him) once said: "If she is trustworthy." And on another occasion he said: "If she is just, then she should be made to swear by Allah that she has breastfed them; if she takes the oath, then separation should be made between the two of them." Hushaym said: "We do not act upon this."

It is narrated from Hasan al-Basri (may Allah have mercy on him) that he used to say: "A man can have his child breastfed by a Jewish woman, a Christian woman, or an immoral (bad) woman."

A narration from Ibrahim Nakha'i (may Allah have mercy on him) is also reported in the same way, except that he did not mention "Fajirah".

Umar bin Habib narrates from a man (who was probably from the tribe of Kinanah), he says: I was sitting with Abdullah bin Umar (may Allah be pleased with them), he asked: "Are you from such-and-such tribe?" I said: "No, but they have suckled me." So Sayyiduna Umar bin Khattab (may Allah be pleased with them) said: "There can be doubt regarding milk."
