Surah An-Nisa' (The Women), Verse 111

وَمَنْ یَّكْسِبْ اِثْمًا فَاِنَّمَا یَكْسِبُهٗ عَلٰی نَفْسِهٖ وَكَانَ اللّٰهُ عَلِیْمًا حَكِیْمًا ۟

Wa mai yaksib isman fa innamaa yaksibuhoo 'alaa nafsih; wa kaanal laahu 'Aleeman hakeemaa

“And if any one earns sin. he earns it against His own soul: for Allah is full of knowledge and wisdom.”
