حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا عَبْدُ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ عَطَاءِ بْنِ يَزِيدَ، عَنْ تَمِيمٍ الدَّارِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّمَا الدِّينُ النَّصِيحَةُ " . قَالُوا لِمَنْ يَا رَسُولَ اللَّهِ قَالَ " لِلَّهِ وَلِكِتَابِهِ وَلِرَسُولِهِ وَلأَئِمَّةِ الْمُسْلِمِينَ وَعَامَّتِهِمْ " .
