البيهقي:١٤٥٨أَخْبَرَنَاهُ أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو بَكْرِ بْنُ الْحَسَنِ قَالَا ثنا أَبُو الْعَبَّاسِ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ إِسْحَاقَ ثنا الْأَسْوَدُ بْنُ عَامِرٍ ثنا حَمَّادُ بْنُ سَلَمَةَ عَنْ مَطَرٍ عَنْ عَمَّارِ بْنِ أَبِي عَمَّارٍ عَنِ ابْنِ عَبَّاسٍ قَالَ

مَنْ غَسَّلَ مَيِّتًا فَلْيَغْتَسِلْ كَذَا رُوِيَ عَنْهُ بِهَذَا الْإِسْنَادِ وَالصَّحِيحُ عَنِ ابْنِ عَبَّاسٍ خِلَافُ ذَلِكَ
