Everyone will be requited according to His Deeds

 أعوذ بالله من الشيطان الرجيم

 مَّنْ عَمِلَ صَٰلِحًا فَلِنَفْسِهِ ۦ ۖ وَمَنْ أَسَآءَ فَعَلَيْهَا ۗ وَمَا رَبُّكَ بِظَلَّٰمٍ لِّلْعَبِيدِ 

Whoever does righteousness - it is for his [own] soul; and whoever does evil [does so] against it. And your Lord is not ever unjust to [His] servants.

Commentary of Ibn Kathir

Everyone will be requited according to His Deeds

 مَّنْ عَمِلَ صَـلِحاً فَلِنَفْسِهِ 

 (Whosoever does righteous good deed, it is for himself;) means, the benefit of which will come to him.

 وَمَنْ أَسَآءَ فَعَلَيْهَا 

(and whosoever does evil, it is against himself.) means, the consequences of that will come back on him.

 وَمَا رَبُّكَ بِظَلَّـمٍ لِّلْعَبِيدِ

(And your Lord is not at all unjust to (His) servants) means, He only punishes people for their sins, and He does not punish anyone except after establishing proof against him and sending a Messenger to him.

Commentary of Tazkirul Qur'an

When the Truth was revealed through previous prophets, some people accepted it while others did not. The same thing happened when the last of the prophets was raised. Why does man give the Truth such indifferent treatment? The reason for this is the existence of the present conditions for man’s trial. In the present world of trial, whenever Truth appears, a veil is attached to it which screens it from human vision. This veil, which was required to be torn asunder, is then turned into a source of doubt. But this doubt cannot be an excuse for anybody on the Day of Judgement, because it proves that man was not serious about the issue of Truth. Man is perfectly serious in the matter of his worldly interests and therefore he tears down all the veils and discovers the reality. Similarly, if he were to become serious about his ‘other-worldly’ interests, he would pull down all the veils of doubt and see reality as it actually is.
