It was narrated that Anas said: "When one of their womenfolk menstruated, the Jews would not eat or drink with them, nor mix with them in their houses. They asked the Prophet of Allah ( صلی اللہ علیہ وسلم ) about that, and Allah the Mighty and Sublime revealed: The ask you concerning menstruation. Say: 'That is an Adha (a harmful thing).' [2] So the Messenger of Allah ( صلی اللہ علیہ وسلم ) commanded them to eat and drink with them (menstruating women) and to mix with them in their houses, and to do everything with them except intercourse. The Jews said: 'The Messenger of Allah ( صلی اللہ علیہ وسلم ) does not leave anything against it.' Usaid bin Hudair and 'Abbad bin Bishr went and told the Messenger of Allah ( صلی اللہ علیہ وسلم ) and they said: 'Should we have intercourse with them when they are menstruating?' The expression of the Messenger of Allah ( صلی اللہ علیہ وسلم ) changed greatly until we thought that he was angry with them, and they left. Then the Messenger of Allah ( صلی اللہ علیہ وسلم ) received a gift of milk, so he sent someone to bring them back and he gave them some to drink, so they knew that he was not angry with them."
