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.

I and the Messenger of Allah ﷺ used to lie in one cloth at night while I was menstruating. If anything from me smeared him, he washed the same place (that was smeared), and did not wash beyond it. If anything from him smeared his clothe, he washed the same place and did not wash beyond that, and prayed with it (i.e. the clothe).  

سَمِعْتُ عَائِشَةَ ؓ تَقُولُ كُنْتُ أَنَا وَرَسُولُ اللَّهِ ﷺ نَبِيتُ فِي الشِّعَارِ الْوَاحِدِ وَأَنَا حَائِضٌ طَامِثٌ فَإِنْ أَصَابَهُ مِنِّي شَىْءٌ غَسَلَ مَكَانَهُ وَلَمْ يَعْدُهُ وَإِنْ أَصَابَ تَعْنِي ثَوْبَهُ مِنْهُ شَىْءٌ غَسَلَ مَكَانَهُ وَلَمْ يَعْدُهُ وَصَلَّى فِيهِ  

Maimunah daughter of Al Harith said “When the Apostle of Allaah ﷺ intended to associate and lie with any of his wives who was menstruating, he ordered her to wrap up the lower garment(loin-cloth) and then he had association with her.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا أَرَادَ أَنْ يُبَاشِرَ امْرَأَةً مِنْ نِسَائِهِ وَهِيَ حَائِضٌ أَمَرَهَا أَنْ تَتَّزِرَ ثُمَّ يُبَاشِرُهَا
