325. hadíth
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ لِبَعْضِ أَصْحَابِهِ: «اِسْتَأْصِلْ شَعْرَكَ يَقِلُّ دَرَنُهُ وَ دَوَابُّهُ وَ وَسَخُهُ وَ تَغْلُظُ رَقَبَتُكَ وَ يَجْلُو بَصَرَكَ وَ يَسْتَرِيحُ بَدَنُكَ.
Imam Jafar ibn Muhammad Al-Sadiq (a.s) said to some of his companions: "Cut your hair short to reduce its dirt, pests, and grime; it will strengthen your neck, improve your eyesight, and provide relief for your body."
