البيهقي:٣٣٠٩ – وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو قَالَا ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا يَحْيَى بْنُ أَبِي طَالِبٍ ثنا عَبْدُ الْوَهَّابِ هُوَ ابْنُ عَطَاءٍ أنبأ سَعِيدٌ يَعْنِي ابْنَ أَبِي عَرُوبَةَ عَنْ عِسْلٍ عَنْ عَطَاءٍ عَنْ أَبِي هُرَيْرَةَ

أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنِ السَّدْلِ فِي الصَّلَاةِ وَصَلَهُ الْحَسَنُ بْنُ ذَكْوَانَ عَنْ سُلَيْمَانَ عَنْ عَطَاءٍ وَعِسْلٍ عَنْ عَطَاءٍ وَأَرْسَلَهُ عَامِرٌ الْأَحْوَلُ عَنْ عَطَاءٍ
