Al-Jathiyah 45:15
مَنْ عَمِلَ صَـٰلِحًا فَلِنَفْسِهِۦ ۖ وَمَنْ أَسَآءَ فَعَلَيْهَا ۖ ثُمَّ إِلَىٰ رَبِّكُمْ تُرْجَعُونَ
Man AAamila salihanfalinafsihi waman asaa faAAalayha thumma ilarabbikum turjaAAoon
Whoever does a good deed - it is for himself; and whoever does evil - it is against it [i.e., the self or soul]. Then to your Lord you will be returned.
Whoever acts righteously, it is for his own benefit, and who does evil, it is against his own soul. Then towards your Lord, you will be returned.
