Al-Kāfi|Volume 6|Book 7|Chapter 35
مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَمَّنْ ذَكَرَهُ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ ذَكَرْنَا الْأَخْذَ مِنَ الشَّارِبِ فَقَالَ نُشْرَةٌ وَ هُوَ مِنَ السُّنَّةِ .
8. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from those whom he has mentioned who has said the following: “Once we mentioned trimming the mustache before abu ‘Abd Allah عليه السلام. He (the Imam) said, ‘It is a charm and trimming it is of Sunnah.”’
