Messenger of Allah ﷺ said, "To shave the pubic hair. to clip the nails and to cut the moustaches short, are characteristics of the Fitra."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مِنَ الْفِطْرَةِ حَلْقُ الْعَانَةِ وَتَقْلِيمُ الأَظْفَارِ وَقَصُّ الشَّارِبِ  

I heard the Prophet ﷺ saying. "Five practices are characteristics of the Fitra: circumcision, shaving the pubic hair, cutting the moustaches short, clipping the nails, and depilating the hair of the armpits."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الْفِطْرَةُ خَمْسٌ الْخِتَانُ وَالاِسْتِحْدَادُ وَقَصُّ الشَّارِبِ وَتَقْلِيمُ الأَظْفَارِ وَنَتْفُ الآبَاطِ  

Ibn ʿUmar said, The Prophet ﷺ said, 'Do the opposite of what the pagans do. Keep the beards and cut the moustaches short.' Whenever Ibn ʿUmar performed the Hajj or ʿUmra, he used to hold his beard with his hand and cut whatever remained outside his hold.  

عَنِ النَّبِيِّ ﷺ قَالَ خَالِفُوا الْمُشْرِكِينَ وَفِّرُوا اللِّحَى وَأَحْفُوا الشَّوَارِبَ وَكَانَ ابْنُ عُمَرَ إِذَا حَجَّ أَوِ اعْتَمَرَ قَبَضَ عَلَى لِحْيَتِهِ فَمَا فَضَلَ أَخَذَهُ
