"The Messenger of Allah 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.'" (Using translation from Ibn Mājah 292)
أَنَّ رَسُولَ اللهِ ﷺ وَقَالَ سُفْيَانُ مَرَّةً رِوَايَةً خَمْسٌ مِنَ الْفِطْرَةِ الْخِتَانُ وَالِاسْتِحْدَادُ وَقَصُّ الشَّارِبِ وَتَقْلِيمُ الْأَظْفَارِ وَنَتْفُ الْإِبْطِ
