Arabic (Original)
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ اللَّهُ إِذَا تَحَدَّثَ عَبْدِي بِأَنْ يَعْمَلَ حَسَنَةً فَأَنَا أَكْتُبُهَا لَهُ حَسَنَةً مَا لَمْ يَفْعَلْ فَإِذَا عَمِلَهَا فَأَنَا أَكْتُبُهَا لَهُ بِعَشْرَةِ أَمْثَالِهَا وَإِذَا تَحَدَّثَ بِأَنْ يَفْعَلَ سَيِّئَةً فَأَنَا أَغْفِرُهَا مَا لَمْ يَفْعَلْهَا فَإِذَا عَمِلَهَا فَأَنَا أَكْتُبُهَا لَهُ بِمِثْلِهَا.
English Translation
The Messenger of Allah (peace be upon him) said: 'Allah said: When My servant thinks about doing a good deed, I record it as one good deed for him even if he has not yet done it. If he does it, I record it for him as ten times its like. When he thinks about committing a sin, I forgive it as long as he does not do it. If he does it, I record it for him as just one sin.'
