٦ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْعَبَّاسِ بْنِ عَامِرٍ عَنْ أَبَانٍ عَنْ رَجُلٍ لا نَعْلَمُهُ إِلا يَحْيَى الأزْرَقَ قَالَ قَالَ لِي أَبُو الْحَسَنِ (صَلَّى اللهُ عَلَيْهِ وآلِه) مَنْ ذَكَرَ رَجُلاً مِنْ خَلْفِهِ بِمَا هُوَ فِيهِ مِمَّا عَرَفَهُ النَّاسُ لَمْ يَغْتَبْهُ وَمَنْ ذَكَرَهُ مِنْ خَلْفِهِ بِمَا هُوَ فِيهِ مِمَّا لا يَعْرِفُهُ النَّاسُ اغْتَابَهُ وَمَنْ ذَكَرَهُ بِمَا لَيْسَ فِيهِ فَقَدْ بَهَتَهُ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al- ‘ Abbas ibn ‘Amir from Aban from a man we do not know except Yahya al- Azraq who has said the following: “Abu al-Hassan  once said to me, ‘Anyone’s mentioning a man behind his back with something that is found in him and people know is not backbiting. Whoever mentions a person behind his back with something that is found in him and people do not know it, he has backbitten him. Whoever mentions a person with something that is not found in him has accused him falsely.’”
