البيهقي:٧٦١أَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ بِشْرَانَ الْعَدْلُ بِبَغْدَادَ أنا أَبُو الْحَسَنِ عَلِيُّ بْنُ مُحَمَّدٍ الْمُقْرِئُ ثنا ابْنُ أَبِي مَرْيَمَ ثنا الْفِرْيَابِيُّ ثنا سُفْيَانُ عَنْ عَمْرِو بْنِ عَامِرٍ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

كَانَ رَسُولُ اللهِ ﷺ يَتَوَضَّأُ عِنْدَ كُلِّ صَلَاةٍ وَكَانَ أَحَدُنَا يَكْفِيهِ الْوُضُوءُ مَا لَمْ يُحَدِثْ  

رَوَاهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنْ مُحَمَّدِ بْنِ يُوسُفَ الْفِرْيَابِيِّ
