Narrated by:'Aishah said
It was narrated that 'Aishah said:"The Messenger of Allah said: 'Perform ablution after (eating) that which has been changed by fire.'"
حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنَا ابْنُ وَهْبٍ، أَنْبَأَنَا يُونُسُ بْنُ يَزِيدَ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ " .
