Sunan Ibn Majah, Hadith 636 ⓘ
It was narrated that 'Aishah said: "If one of us was menstruating, the Messenger of Allah would tell her to tie her waist-wrapper around herself, then he would embrace her."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ كَانَتْ إِحْدَانَا إِذَا حَاضَتْ أَمَرَهَا النَّبِيُّ ـ صلى الله عليه وسلم ـ أَنْ تَأْتَزِرَ بِإِزَارٍ ثُمَّ يُبَاشِرُهَا .
