Surah Al-Jathiyah (The Kneeling), Verse 15

مَنْ عَمِلَ صَالِحًا فَلِنَفْسِهٖ وَمَنْ اَسَآءَ فَعَلَیْهَا ثُمَّ اِلٰی رَبِّكُمْ تُرْجَعُوْنَ ۟

Man 'amila saalihan falinafsihee wa man asaaa'a fa'alaihaa summa ilaa Rabbikum turja'oon

“If any one does a righteous deed, it ensures to the benefit of his own soul; if he does evil, it works against (his own soul). In the end will ye (all) be brought back to your Lord.”
