The Fitrah (natural inclination of man)
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " الْفِطْرَةُ خَمْسٌ - أَوْ خَمْسٌ مِنَ الْفِطْرَةِ - الْخِتَانُ وَالاِسْتِحْدَادُ وَتَقْلِيمُ الأَظْفَارِ وَنَتْفُ الإِبِطِ وَقَصُّ الشَّارِبِ " .
It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'The deeds connected to the Fitrah are five (or five things are connected to the Fitrah): circumcision, shaving the pubic hairs, clipping the nails, plucking the armpit hairs and trimming the mustache.'"
