2ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ أَبِي شَيْبَةَ عَنِ الزُّهْرِيِّ عَنْ أَبِي جَعْفَرٍ (عَلَيهِ السَّلام) قَالَ بِئْسَ الْعَبْدُ عَبْدٌ يَكُونُ ذَا وَجْهَيْنِ وَذَا لِسَانَيْنِ يُطْرِي أَخَاهُ شَاهِداً وَيَأْكُلُهُ غَائِباً إِنْ أُعْطِيَ حَسَدَهُ وَإِنِ ابْتُلِيَ خَذَلَهُ.
2. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from ‘Uthman ibn ‘Isa from abu Shaybah from al-Zuhri from abu ‘Ja’far (a.s.) who has said the following: “The worst servant (of Allah) is a servant who has two faces and tongues. He praises his brother (in belief) on his face and backbites him in his absence. If his brother (in belief) gains something, he envies him, and if he faces difficult conditions, he betrays him.”
