Hadith on Sunnah: Trimming moustache, letting beard grow

Ibn Umar reported: The Prophet, peace and blessings be upon him, said, “Be different from the idolaters. Let the beard grow and trim the moustache.” Whenever Ibn Umar, may Allah be pleased with him, performed the Hajj or Umrah pilgrimage, he would grab hold of his beard and cut what was beyond his grasp.

عَنْ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ خَالِفُوا الْمُشْرِكِينَ وَفِّرُوا اللِّحَى وَأَحْفُوا الشَّوَارِبَ وَكَانَ ابْنُ عُمَرَ رضي الله عنه إِذَا حَجَّ أَوْ اعْتَمَرَ قَبَضَ عَلَى لِحْيَتِهِ فَمَا فَضَلَ أَخَذَهُ
