Fondling The Menstruating Woman
Sunan an-Nasai
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ كَانَتْ إِحْدَانَا إِذَا حَاضَتْ أَمَرَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ تَتَّزِرَ ثُمَّ يُبَاشِرُهَا .
It was narrated that 'Aishah said: "If one of us was menstruating, the Messenger of Allah (ﷺ) would tell her to put on an Izar (waist wrap) then he would fondle her."
