It is narrated from Sayyiduna Anas (may Allah be pleased with him) that on the morning when the Prophet Muhammad (peace and blessings be upon him) consummated his marriage with Sayyidah Zainab (may Allah be pleased with her) and held the wedding feast (walimah), I invited people to participate in it. The Prophet (peace and blessings be upon him) satisfied the people with bread and meat. Then he returned as he would return to the chambers of his wives. The Prophet (peace and blessings be upon him) greeted them with peace, and they prayed for him. Then the Prophet (peace and blessings be upon him) returned towards his house, and I was with him. When the Prophet (peace and blessings be upon him) reached the house, there were still two men in a corner talking to each other. When the Prophet (peace and blessings be upon him) saw them, he turned back. When those two men saw the Prophet (peace and blessings be upon him), they quickly left the house. Now, I do not know whether I informed the Prophet (peace and blessings be upon him) of their departure or he was informed. Then the Prophet (peace and blessings be upon him) returned towards his house and hung a curtain between himself and me, and the verse of the curtain (hijab) was revealed.
