It was narrated that 'Aishah said:
Aflah, the brother of Abu Al-Qu'ais, who was my paternal uncle through breast-feeding, used to ask permission to enter upon me, and I refused to let him in until the Messenger of Allah came, and I told him about that. He said: 'Let him in, for he is your paternal uncle.' 'Aishah said: That was after the (Verse of) Hijab had been revealed.
