8ـ أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنِ ابْنِ فَضَّالٍ عَنْ أَبِي جَمِيلَةَ عَنْ مُحَمَّدِ بْنِ حُمْرَانَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ إِذَا هَمَّ أَحَدُكُمْ بِخَيْرٍ أَوْ صِلَةٍ فَإِنَّ عَنْ يَمِينِهِ وَشِمَالِهِ شَيْطَانَيْنِ فَلْيُبَادِرْ لا يَكُفَّاهُ عَنْ ذَلِكَ.
8. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from ibn Faddal from abu Jamilah from Muhammad ibn Humran from Abu ‘Abdillah (a.s.) who has said the following: “When one of you intends to perform a good deed or establish good relations there will be two Satans, one on each side. He, thus, should perform it immediately before they prevent him from the good deed.”
