الآية رقم (111) - وَمَن يَكْسِبْ إِثْمًا فَإِنَّمَا يَكْسِبُهُ عَلَى نَفْسِهِ وَكَانَ اللّهُ عَلِيمًا حَكِيمًا

(111) - {And whoever commits a sin only earns it against himself. And Allah is ever Knowing and Wise.}

Allah (swt) says the word (earns) because this man thinks that this sin is for his sake, but indeed it is (against) himself and Allah (swt) is ever Knowing what he intends and what he does.
