10ـ أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنِ ابْنِ أَبِي نَجْرَانَ عَنْ عُمَرَ بْنِ يَزِيدَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) أَنَّهُ قَالَ لا تَصْحَبُوا أَهْلَ الْبِدَعِ وَلا تُجَالِسُوهُمْ فَتَصِيرُوا عِنْدَ النَّاسِ كَوَاحِدٍ مِنْهُمْ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) الْمَرْءُ عَلَى دِينِ خَلِيلِهِ وَقَرِينِهِ.
10. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from ibn abu Najran from ‘Umar ibn Yazid from Abu ‘Abdillah who has said the following: “Do not befriend blasphemers and do not associate with them; people may consider you as one of them. The Messenger of Allah has said, ‘A man follows the religion of his friend and associates.’”
