Surah An-Nisa, ayah 111

وَمَن يَكۡسِبۡ إِثۡمٗا فَإِنَّمَا يَكۡسِبُهُۥ عَلَىٰ نَفۡسِهِۦۚ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمٗا ١١١

Waman yaksib ithman fa innamā yaksibuhū 'alā nafsihī wakānallāhu 'alīman hakīmā

And whoever earns [i.e., commits] a sin only earns it against himself. And Allāh is ever Knowing and Wise.
