أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، عَنْ بِشْرٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِسْحَاقَ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " خَمْسٌ مِنَ الْفِطْرَةِ الْخِتَانُ وَحَلْقُ الْعَانَةِ وَنَتْفُ الضَّبْعِ وَتَقْلِيمُ الظُّفْرِ وَتَقْصِيرُ الشَّارِبِ " . وَقَفَهُ مَالِكٌ .
