3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ يُوسُفَ عَنْ مُيَسِّرٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ لا يَنْبَغِي لِلْمَرْءِ الْمُسْلِمِ أَنْ يُوَاخِيَ الْفَاجِرَ وَلا الأحْمَقَ وَلا الْكَذَّابَ.
3. A number of our people have narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Muhammad ibn Yusuf from Maysir from Abu ‘Abdillah (a.s.) who has said the following: “It is not proper for a Muslim man to become friends with an indecent, an idiot and a liar.”
