أَخْبَرَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ زُبَيْدٍ، عَنْ إِبْرَاهِيمَ، عَنْ مَسْرُوقٍ، عَنْ عَبْدِ اللَّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لَيْسَ مِنَّا مَنْ ضَرَبَ الْخُدُودَ وَشَقَّ الْجُيُوبَ وَدَعَا بِدَعْوَى الْجَاهِلِيَّةِ " .
