COMMENTARY on 4:111
A. Yusuf Ali:

Translation:
And if any one earns 624 sin. he earns it against His own soul: for Allah is full of knowledge and wisdom.
Commentary:

624  Kasaba-to earn, to gain, to work for something valuable, to lay up a provision for the future life. We do a day's labor to earn our livelihood; so in a spiritual sense, whatever good or evil we do in this life, earns us good or evil in the life to come. Inverses 110-112 three cases are considered: (1) if we do ill, and repent. Allah will forgive: (2) if we do ill and do not repent, thinking that we can hide it, we are wrong; nothing is hidden from Allah, and we shall suffer the full consequences in the life to come, for we can never evade our personal responsibility: (3) if we do ill, great or small, and impute it to another, our original responsibility for the ill remains, but we add to it something else; for we tie round our necks the guilt of falsehood, which converts even our minor fault into a great sin, and in any case brands us even in this life with shame and ignominy.

 

Muhammad Asad:

Translation:
for he who commits a sin, commits it only to his own hurt; 137 and God is indeed all-knowing, wise.
Commentary:
137  Lit., "he who earns a sin, earns it only against himself".
