that he was a boy of ten at the time when the Prophet (ﷺ) emigrated to Medina. He added: I served Allah's
Apostle for ten years (the last part of his life time) and I know more than the people about the
occasion whereupon the order of Al-Hijab was revealed (to the Prophet). Ubai b n Ka`b used to ask
me about it. It was revealed (for the first time) during the marriage of Allah's Messenger (ﷺ) with Zainab bint
Jahsh. In the morning, the Prophet (ﷺ) was a bride-groom of her and he Invited the people, who took their
meals and went away, but a group of them remained with Allah's Messenger (ﷺ) and they prolonged their
stay. Allah's Messenger (ﷺ) got up and went out, and I too, went out along with him till he came to the lintel
of `Aisha's dwelling place. Allah's Messenger (ﷺ) thought that those people had left by then, so he returned,
and I too, returned with him till he entered upon Zainab and found that they were still sitting there and
had not yet gone. The Prophet (ﷺ) went out again, and so did I with him till he reached the lintel of
`Aisha's dwelling place, and then he thought that those people must have left by then, so he returned,
and so did I with him, and found those people had gone. At that time the Divine Verse of Al-Hijab
was revealed, and the Prophet (ﷺ) set a screen between me and him (his family).
Sahih al-Bukhari Book 79, Hadith 12
Among the jews, when a women menstruated, they ejected her from the house, and they did not eat with her, nor did they drink with her, nor did they associate with her in (their houses) so the Messenger of Allah (May peace be upon him) was questioned about that. Thereupon Allah revealed : “They question thee concerning menstruation. Say : I: is an illness, so let woman alone at such times” (ii 222). The Messenger of Allah (May peace be upon him) then said: Associate with them in the houses and do everything except sexual intercourse. Thereupon the Jews said: This man does not want to leave anything we do without opposing us in it. Usaid b. Hudair and Abbad b. Bishr came and said: Messenger of Allah, the jews are saying such and such a thing. Shall we not then have intercourse with women during mensuration? The face of the Apostle Allah(ﷺ) underwent such a change that we thought he was angry with them; but when they went out they received a gift of milk which was being brought to the Messenger of Allah(ﷺ), and he sent after them and gave them a drink, whereupon we thought that he was not angry with them.
