bukhari:5892Muḥammad b. Minhāl > Yazīd b. Zurayʿ > ʿUmar b. Muḥammad b. Zayd > Nāfiʿ > Ibn ʿUmar

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.  

البخاري:٥٨٩٢حَدَّثَنَا مُحَمَّدُ بْنُ مِنْهَالٍ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ حَدَّثَنَا عُمَرُ بْنُ مُحَمَّدِ بْنِ زَيْدٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

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