Anas bin Malik said Among the Jews when a woman menstruated, they did not eat with her and drink with her and did not associate with her in their houses, so the Apostle of Allaah (ﷺ) was questioned about it. Hence, Allah the Exalted revealed "And they ask you about menstruation,. Say "It is harmful, so keep aloof from women during menstruation till the end of the verse. The Apostle of Allaah (ﷺ) said "Associate with them in the houses and do everything except sexual intercourse. The Jews thereupon said "This man does not leave anything we do without opposing us in it. Usaid bin Hudair and Abbad bin Bishr came to the Apostle of Allaah (ﷺ) and said, Apostle of Allaah (ﷺ) the Jews are saying such and such. Shall we not have intercourse with them during their menstruation? The face of the Apostle of Allaah (ﷺ) underwent such a change that we thought he was angry with them, so they went out. They were met by a gift of milk which was being brought to the Apostle of Allaah (ﷺ) and he sent after them, whereby we felt that he was not angry with them.
