Lady Aisha (may Allah be pleased with her) said: My foster uncle came to me and asked permission to enter. I said: I will not give permission without asking the Messenger of Allah (peace be upon him). When the Messenger of Allah (peace be upon him) came, I asked him. He (peace be upon him) said: "He is your uncle, so give him permission to enter." I said: O Messenger of Allah (peace be upon him)! It was a woman who suckled me, what does a man have to do with that? He (peace be upon him) said: "He is your uncle, indeed he may come to you." And this conversation took place after the verse of Hijab had been revealed. Lady Aisha (may Allah be pleased with her) said: The relationships that are forbidden by lineage are also forbidden by suckling.
