Menstruation - Section 1
وَعَن عَائِشَة قَالَتْ: كُنْتُ أَغْتَسِلُ أَنَا وَالنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ إِنَاءٍ وَاحِدٍ وَكِلَانَا جُنُبٌ وَكَانَ يَأْمُرُنِي فَأَتَّزِرُ فَيُبَاشِرُنِي وَأَنَا حَائِضٌ وَكَانَ يُخْرِجُ رَأْسَهُ إِلَيَّ وَهُوَ مُعْتَكِفٌ فَأَغْسِلُهُ وَأَنَا حَائِض
‘A'isha said, “The Prophet (ﷺ) and I used to wash from one vessel when we were both sexually defiled. When I was menstruating he would order me to wrap myself up and would embrace me. And when he was observing prayer in seclusion, he would put out his head for me and I would wash it when I was menstruating. (Bukhari and Muslim.)
