Surah Fussilat, Verse 46

مَّنۡ عَمِلَ صَٰلِحٗا فَلِنَفۡسِهِۦۖ وَمَنۡ أَسَآءَ فَعَلَيۡهَاۗ وَمَا رَبُّكَ بِظَلَّٰمٖ لِّلۡعَبِيدِ٤٦

man ʿamila ṣāliḥan falinafsihi waman asāa faʿalayhā wamā rabbuka biẓallāmin lil'ʿabīdi

Whoever does righteousness - it is for his [own] soul; and whoever does evil [does so] against it. And your Lord is not ever unjust to [His] servants.
