Lady Aisha (may Allah be pleased with her) said: She was with the Messenger of Allah (peace be upon him) in the house of Lady Hafsa (may Allah be pleased with her) when she heard the voice of a man and said: O Messenger of Allah! I heard the sound of a man entering your house? The Messenger of Allah (peace be upon him) said: "I think it is such-and-such a man." He was the foster uncle of Lady Hafsa (may Allah be pleased with her). Lady Aisha (may Allah be pleased with her) said: O Messenger of Allah! If my foster uncle were alive, could he enter my house? The Messenger of Allah (peace be upon him) said: "Yes, the prohibition (of marriage) established by suckling is the same as that established by birth."
