أَخْبَرَنَا هَنَّادُ بْنُ السَّرِيِّ، عَنْ أَبِي بَكْرِ بْنِ عَيَّاشٍ، عَنْ أَبِي حَصِينٍ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، قَالَ قَالَ عَلِيٌّ كُنْتُ رَجُلاً مَذَّاءً وَكَانَتِ ابْنَةُ النَّبِيِّ صلى الله عليه وسلم تَحْتِي فَاسْتَحْيَيْتُ أَنْ أَسْأَلَهُ فَقُلْتُ لِرَجُلٍ جَالِسٍ إِلَى جَنْبِي سَلْهُ ‏.‏ فَسَأَلَهُ فَقَالَ ‏ "‏ فِيهِ الْوُضُوءُ ‏"‏ ‏.‏
