It is narrated from Hazrat Anas (may Allah be pleased with him) that on the first night the Prophet (peace and blessings be upon him) stayed with Hazrat Zainab bint Jahsh (may Allah be pleased with her), the next morning the Prophet (peace and blessings be upon him) gave a wedding feast (walima) and fed the Muslims plenty of bread and meat. Then, as usual, he returned and went to the houses of the pure wives and greeted them, and they prayed for the Prophet (peace and blessings be upon him). Then he returned again, and when he reached home, he saw that two men were sitting in a corner of the house talking to each other. The Prophet (peace and blessings be upon him), seeing them, turned back. When those two saw the Prophet (peace and blessings be upon him) turning back from his house, they quickly stood up. Now I do not remember whether I informed the Prophet (peace and blessings be upon him) of their departure or someone else did. In any case, the Prophet (peace and blessings be upon him) returned home and hung a curtain between me and himself, and the verse of hijab was revealed.
