قَالَ ابْنُ شِهَابٍ أَخْبَرَنِي سَعِيدُ بْنُ خَالِدِ بْنِ عَمْرِو بْنِ عُثْمَانَ، وَأَنَا أُحَدِّثُهُ، هَذَا الْحَدِيثَ . أَنَّهُ سَأَلَ عُرْوَةَ بْنَ الزُّبَيْرِ عَنِ الْوُضُوءِ، مِمَّا مَسَّتِ النَّارُ فَقَالَ عُرْوَةُ سَمِعْتُ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم تَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم "تَوَضَّئُوا مِمَّا مَسَّتِ النَّارُ "
