It is narrated from Hazrat Anas (may Allah be pleased with him) that at the time of the Prophet’s (peace and blessings be upon him) arrival in Madinah Munawwarah, his age was ten years. He says that his mother used to encourage him to serve the Prophet (peace and blessings be upon him), therefore, when the command of veil (purdah) was revealed, I knew the situation of that time better than anyone else. That night, the Prophet (peace and blessings be upon him) had seclusion with Hazrat Zainab (may Allah be pleased with her), and in the morning the Prophet (peace and blessings be upon him) was a bridegroom. After that, the Prophet (peace and blessings be upon him) invited the people, they came, ate food, and left, but some people remained sitting there and stayed for quite a while, until the Prophet (peace and blessings be upon him) himself got up and went outside. I also went outside so that they might leave as well. The Prophet (peace and blessings be upon him) and I, while walking, stopped at the threshold of Hazrat Aisha’s (may Allah be pleased with her) chamber. The Prophet (peace and blessings be upon him) thought that perhaps those people had now left, so the Prophet (peace and blessings be upon him) returned, and I was with him. When we saw, indeed those people had gone. Then the Prophet (peace and blessings be upon him) entered inside and hung a curtain, and Allah revealed the verse of hijab.
