Fussilat 41:46

مَّنْ عَمِلَ صَـٰلِحًا فَلِنَفْسِهِۦ ۖ وَمَنْ أَسَآءَ فَعَلَيْهَا ۗ وَمَا رَبُّكَ بِظَلَّـٰمٍ لِّلْعَبِيدِ

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.
