It is narrated from Hazrat Anas (may Allah be pleased with him) that among the Jews, when a woman was menstruating, they would neither eat nor drink with her, nor would they stay together in the same house. The noble Companions (may Allah be pleased with them) asked the Prophet (peace and blessings be upon him) about this, so Allah Almighty revealed this verse: "They ask you about menstruating women. Say: It is a harm, so keep away from women during menstruation and do not approach them until they are purified." After reciting this verse in full, the Prophet (peace and blessings be upon him) said: "You may do everything except intercourse." When the Jews learned of this, they said: "This man opposes us in every matter." Then Hazrat Usayd bin Hudair (may Allah be pleased with him) and Abbad bin Bishr (may Allah be pleased with him) came to the service of the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him)! The Jews are saying such and such things, should we not even go near our wives? (So that we may completely oppose the Jews.)" Upon hearing this, the color of the blessed face of the Prophet (peace and blessings be upon him) changed, and we understood that the Prophet (peace and blessings be upon him) was displeased with them. Both of them also left from there, but shortly after, a gift of milk arrived for the Prophet (peace and blessings be upon him), so the Prophet (peace and blessings be upon him) called both of them and gave it to them to drink. In this way, they understood that the Prophet (peace and blessings be upon him) was not displeased with them. Imam Ahmad (may Allah have mercy on him) says that Hammad bin Salamah (may Allah have mercy on him) would not praise the chain of narration of any hadith among his ahadith, but due to the excellence of the chain of this hadith, he praised it greatly.
