It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he was ten years old when the Messenger of Allah (peace and blessings be upon him) came to Madinah. He said: "My mothers used to keep me constantly at the service of the Messenger of Allah (peace and blessings be upon him)." He said: "So I served him (peace and blessings be upon him) for ten years of his blessed life in Madinah, and when the Messenger of Allah (peace and blessings be upon him) passed away I was twenty years old." He said: "When (the command of) the hijab was revealed, I knew about it better than all the people; Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) too used to ask me about it." He said: "It was first revealed on the occasion when the Messenger of Allah (peace and blessings be upon him) consummated his marriage with Sayyidah Zaynab bint Jahsh (may Allah be pleased with her). the Messenger of Allah (peace and blessings be upon him) began the morning with her as a bridegroom, so he (peace and blessings be upon him) invited the people; they ate the food and then left, but some of them stayed with the Messenger of Allah (peace and blessings be upon him) and stayed for a long time. So the Messenger of Allah (peace and blessings be upon him) stood up and went out, and I went out with him (peace and blessings be upon him) so that those people would also leave. the Messenger of Allah (peace and blessings be upon him) kept walking and I kept walking with him (peace and blessings be upon him), until he (peace and blessings be upon him) reached the threshold of the apartment of Sayyidah Aishah (may Allah be pleased with her). Then he (peace and blessings be upon him) looked towards those people, (to see) whether they had left. Then he (peace and blessings be upon him) returned and I returned with him (peace and blessings be upon him), until he (peace and blessings be upon him) went in to Sayyidah Zaynab (may Allah be pleased with her), and saw that they had left. Then a screen was drawn between me and them, and the verse of hijab was revealed."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Zuhri in this complete form except Yunus; Hassan bin Ibrahim is alone in narrating it."
