Whereas whoever earns a sin (failing to seek forgiveness for it), earns it only against himself (to his own loss only). And God is All-Knowing, All-Wise
Whoever commits (or reaps, earns the wages or consequences of) a wrong (sin, crime), he only commits it against his own soul, for Allah is Knowing, Wise
Whoever earns a violation against the Permanent Values given in the Qur'an does it against, and drags down, his own "Self". Allah, the Knower, the Wise imparts this information to you
And whoever commits a crime, its consequence are for him alone (nobody else)! Allah is the Aleem, the Hakim.
Sayyed Abbas Sadr-Ameli
And whoever commits a sin, indeed he commits it only against his own self and Allah is All-Knowing, All-Wise.
Al-muntakhab fi tafsir al-Qur'an al-Karim
And he who commits himself to an evil line of conduct will have in effect committed it but against his own soul and to the hurt of his own interest and Allah has always been ever 'Alimun and Hakimun
