Sayyida Aisha Siddiqa (may Allah be pleased with her) narrates: The brother of Abu Qais (may Allah be pleased with him) sought permission to enter my house. This was after the command of hijab had been revealed. So I said: I will not give you permission until the Prophet (peace and blessings of Allah be upon him) comes. When the Prophet (peace and blessings of Allah be upon him) arrived, I asked him for permission regarding this matter. I said: O Messenger of Allah (peace and blessings of Allah be upon him)! The brother of Abu Qais sought permission to enter my house, so I refused to give him permission before asking you, because the wife of Abu Qais had nursed me, but Abu Qais himself had not nursed me. So the Prophet (peace and blessings of Allah be upon him) said: You should have given him permission; he is your uncle.
