quran:41:46 –

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.  

Whoever acts righteously, it is for ˹the good of˺ his own soul, that he acts ˹thus˺, and whoever does evil, it is to the detriment thereof, in other words, the harm consequent from his evildoing will ˹only˺ be to him. And your Lord is not ˹at all˺ a tyrant to His servants, that is, He is not One of injustice, as He, exalted be He, says: Surely God shall not wrong so much as the weight of an atom ˹Q. 4:40˺.
القرآن:٤١:٤٦ –

مَنْ عَمِلَ صَالِحًا فَلِنَفْسِهِ ۖ وَمَنْ أَسَاءَ فَعَلَيْهَا ۗ وَمَا رَبُّكَ بِظَلَّامٍ لِلْعَبِيدِ  

{من عمل صالحاً فلنفسه} عمل {ومن أساء فعليها} أي فضرر إساءته على نفسه {وما ربك بظلام للعبيد} أي بذي ظلم لقوله تعالى (إن الله لا يظلم مثقال ذرة).
