عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللَّهِ عَنْ عَلِيِّ بْنِ إِسْحَاقَ بْنِ سَعْدٍ عَنْ يُونُسَ عَنْ بَعْضِ أَصْحَابِهِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) فِي قَدْرِ اللِّحْيَةِ قَالَ
تَقْبِضُ بِيَدِكَ عَلَى اللِّحْيَةِ وَ تَجُزُّ مَا فَضَلَ .

“Abu ‘Abd Allah , has said, ‘The amount of beard that you must keep is what comes in inside your fist and you must clip off whatever exceeds you fist.’”
