مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَبْدِ اللَّهِ بْنِ جُنْدَبٍ عَنْ سُفْيَانَ بْنِ السِّمْطِ قَالَ قَالَ لِي أَبُو عَبْدِ اللَّهِ ( عليه السلام )
الثَّوْبُ النَّقِيُّ يَكْبِتُ الْعَدُوَّ وَ الدُّهْنُ يَذْهَبُ بِالْبُؤْسِ وَ الْمَشْطُ لِلرَّأْسِ يَذْهَبُ بِالْوَبَاءِ قَالَ قُلْتُ وَ مَا الْوَبَاءُ قَالَ الْحُمَّى وَ الْمَشْطُ لِلِّحْيَةِ يَشُدُّ الْأَضْرَاسَ .
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from ‘Abd Allah ibn Jundab from Sufyan ibn al-Simt who has said the following:
“Abu ‘Abd Allah 
, has said, ‘Clean and fresh clothes saddens the enemy, using oil dispels despair and combing the head removes al-Waba’.’ I then asked, ‘What is al-Waba’?’ He (the Imam) said, ‘It is fever. Combing the beard strengthens molar teeth.’”
