Arabic (Original)
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَتْ الْمَلَائِكَةُ رَبِّ ذَاكَ عَبْدُكَ يُرِيدُ أَنْ يَعْمَلَ سَيِّئَةً وَهُوَ أَبْصَرُ بِهِ فَقَالَ ارْقُبُوهُ فَإِنْ عَمِلَهَا فَاكْتُبُوهَا لَهُ بِمِثْلِهَا وَإِنْ تَرَكَهَا فَاكْتُبُوهَا لَهُ حَسَنَةً إِنَّمَا تَرَكَهَا مِنْ جَرَّايَ.
English Translation
The Messenger of Allah (peace be upon him) said: 'The angels said: O Lord, that servant of Yours intends to commit a sin — and He sees him best. Allah said: Watch him. If he commits it, write it down as one sin for him. If he leaves it, write it down as a good deed for him, for he only left it for My sake.'
