1ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي مُحَمَّدٍ الْوَابِشِيِّ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ احْذَرُوا أَهْوَاءَكُمْ كَمَا تَحْذَرُونَ أَعْدَاءَكُمْ فَلَيْسَ شَيْ‏ءٌ أَعْدَى لِلرِّجَالِ مِنِ اتِّبَاعِ أَهْوَائِهِمْ وَحَصَائِدِ أَلْسِنَتِهِمْ.
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Mahbub from abu Muhammad al-Wabishi who has said the following: “I heard Abu ‘Abdillah (a.s.) saying, ‘Be afraid of your desires just as you fear your enemies. Nothing is a more dangerous enemy to men than following their desires and what their tongues harvest.’”
