الأدب المفرد · Hadith 1051

Anas said that he was ten years old when the Messenger of Allah, may Allah bless him and grant him peace, came to Madina. He said, "My mothers decided that I would serve him and I served him for ten years. He died when I was twenty. I am the person who knows best about the business of the veil. The first instance that was revealed occurred when the Messenger of Allah, may Allah bless him and grant him peace, built a room for Zaynab bint Jahsh. He celebrated the wedding there, invited the people who came, ate and then left. A group remained with the Prophet, may Allah bless him and grant him peace. They stayed for a long time and then the Prophet went out and I went out hoping that they would leave. He walked and I walked with him until he came to the threshold of 'A'isha's room. Then, thinking that they would have left, he returned and I returned with him. He went to Zaynab but they were still sitting there. He left again and I left with him until he once more reached the threshold of 'A'isha's room. When he thought that they would have gone, he went back again and I went back with him. This time they had indeed left. The Prophet, may Allah bless him and grant him peace, then put up a curtain between me and him, and the veil was revealed."
