Chapter 190 | Intending to Perform a Good or an Evil Deed
2ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ الله عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ بْنِ مِهْرَانَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ إِنَّ الْمُؤْمِنَ لَيَهُمُّ بِالْحَسَنَةِ وَلا يَعْمَلُ بِهَا فَتُكْتَبُ لَهُ حَسَنَةٌ وَإِنْ هُوَ عَمِلَهَا كُتِبَتْ لَهُ عَشْرُ حَسَنَاتٍ وَإِنَّ الْمُؤْمِنَ لَيَهُمُّ بِالسَّيِّئَةِ أَنْ يَعْمَلَهَا فَلا يَعْمَلُهَا فَلا تُكْتَبُ عَلَيْهِ.
2. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from ‘Uthman ibn ‘Isa from Sama’a ibn Mehran from abu Basir from Abu ‘Abdillah who has said the following: “A believer may intend to perform a good deed but does not do it, still (the reward for) one good deed will be written for him and if he actually completes it, (the reward for) ten good deeds will be written in his favor. A believer may intend to commit an evil deed but if he does not do it, nothing will be written against him.”
