الجاثية — Al-Jasiyah Ayat 15
مَنْ عَمِلَ صَالِحًا فَلِنَفْسِهٖۚ وَمَنْ اَسَاۤءَ فَعَلَيْهَا ۖ ثُمَّ اِلٰى رَبِّكُمْ تُرْجَعُوْنَ
Man ‘amila ṣāliḥan fa linafsih(ī), wa man asā'a fa ‘alaihā, ṡumma ilā rabbikum turja‘ūn(a).
"Whoever does a good deed - it is for himself; and whoever does evil - it is against the self. Then to your Lord you will be returned."
