مسلم:٩٨٧d – وَحَدَّثَنَاهُ قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا عَبْدُ الْعَزِيزِ يَعْنِي الدَّرَاوَرْدِيَّ عَنْ سُهَيْلٍ بِهَذَا الإِسْنَادِ وَسَاقَ الْحَدِيثَ وَحَدَّثَنِيهِ مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ بَزِيعٍ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ حَدَّثَنَا رَوْحُ بْنُ الْقَاسِمِ حَدَّثَنَا سُهَيْلُ بْنُ أَبِي صَالِحٍ بِهَذَا الإِسْنَادِ وَقَالَ بَدَلَ عَقْصَاءُ عَضْبَاءُ

وَقَالَ فَيُكْوَى بِهَا جَنْبُهُ وَظَهْرُهُ وَلَمْ يَذْكُرْ جَبِينُهُ
