Good deeds multiplied, bad intentions not counted
فَمَنْ هَمَّ بِحَسَنَةٍ فَلَمْ يَعْمَلْهَا كَتَبَهَا اللَّهُ عِنْدَهُ حَسَنَةً كَامِلَةً، فَإِنْ هُوَ هَمَّ بِهَا فَعَمِلَهَا كَتَبَهَا اللَّهُ عَشْرَ حَسَنَاتٍ إِلَى سَبْعِ مِائَةِ ضِعْفٍ
Fa-man hamma bi-hasanatin fa-lam ya'malha katabaha-llahu 'indahu hasanatan kamilah, fa-in huwa hamma biha fa-'amilaha kataba-llahu 'ashra hasanatin ila sab'i mi'ati di'f.
"Whoever intended a good deed and did not do it, Allah records it as a full good deed. If he did it, Allah records it as ten to seven hundred times. If he intended a bad deed and did not do it, Allah records it as a full good deed. If he did it, Allah records it as one bad deed."
Narrated by Ibn Abbas (hadith qudsi). Sahih al-Bukhari 6491, Sahih Muslim 131 · Nawawi's Forty · #37
A short reflection
The arithmetic of mercy — a good intention is already recorded; a stopped bad intention is a good deed; a done good deed is multiplied at least tenfold.
