4:40

إِنَّ اللَّهَ لَا يَظْلِمُ مِثْقَالَ ذَرَّةٍ وَإِن تَكُ حَسَنَةً يُضَاعِفْهَا وَيُؤْتِ مِن لَّدُنْهُ أَجْرًا عَظِيمًا

Indeed, Allah (does) not wrong (as much as) weight (of) an atom. And if there is a good He doubles it and gives from near Him a reward great.

Translations:

Verily, God does not wrong [anyone] by as much as an atom's weight; and if there be a good deed, He will multiply it, and will bestow out of His grace a mighty reward.

God is never unjust in the least degree: If there is any good (done), He doubleth it, and giveth from His own presence a great reward.

Lo! Allah wrongeth not even of the weight of an ant; and if there is a good deed, He will double it and will give (the doer) from His presence an immense reward.

Surely Allah wrongs not the weight of an atom; and if it is a good deed, He multiplies it and gives from Himself a great reward.

Indeed, Allah does not do injustice, [even] as much as an atom's weight; while if there is a good deed, He multiplies it and gives from Himself a great reward.
