Narrated Abu Hurairah:
The Prophet ﷺ as saying: The inborn characteristics of man are five. Another version says: Five things are of the inborn characteristics of man: circumcision, shaving the pubes, plucking out hair under the armpit, paring the nails and clipping the moustaches.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، يَبْلُغُ بِهِ النَّبِيَّ ﷺ
" الْفِطْرَةُ خَمْسٌ أَوْ خَمْسٌ مِنَ الْفِطْرَةِ الْخِتَانُ وَالاِسْتِحْدَادُ وَنَتْفُ الإِبْطِ وَتَقْلِيمُ الأَظْفَارِ وَقَصُّ الشَّارِبِ " .
