Narrated by:'Aishah that
It was narrated from 'Aishah that:If the Prophet wanted to eat when he was sexually impure, he would wash his hands.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ كَانَ إِذَا أَرَادَ أَنْ يَأْكُلَ وَهُوَ جُنُبٌ غَسَلَ يَدَيْهِ .
