Verily, Allah does not treat a believer unjustly in regard to his virtues. He would confer upon him (His blessing) in this world and would give him reward in the Hereafter. And as regards a non-believer, he would be made to taste the reward (of virtue in this world) what he has done for himself so much that when it would be the Hereafter, he would find no virtue for which he should be rewarded.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ لاَ يَظْلِمُ مُؤْمِنًا حَسَنَةً يُعْطَى بِهَا فِي الدُّنْيَا وَيُجْزَى بِهَا فِي الآخِرَةِ وَأَمَّا الْكَافِرُ فَيُطْعَمُ بِحَسَنَاتِ مَا عَمِلَ بِهَا لِلَّهِ فِي الدُّنْيَا حَتَّى إِذَا أَفْضَى إِلَى الآخِرَةِ لَمْ تَكُنْ لَهُ حَسَنَةٌ يُجْزَى بِهَا  

When a non-believer does good he is made to taste Its reward in this world. And so far as the believer is concerned, Allah stores (the reward) of his virtues for the Hereafter and provides him sustenance in accordance with his obedience to Him.  

عَنْ رَسُولِ اللَّهِ ﷺ إِنَّ الْكَافِرَ إِذَا عَمِلَ حَسَنَةً أُطْعِمَ بِهَا طُعْمَةً مِنَ الدُّنْيَا وَأَمَّا الْمُؤْمِنُ فَإِنَّ اللَّهَ يَدَّخِرُ لَهُ حَسَنَاتِهِ فِي الآخِرَةِ وَيُعْقِبُهُ رِزْقًا فِي الدُّنْيَا عَلَى طَاعَتِهِ  

This hadith has been narrated on the authority of Anas b. Malik through another chain of transmitters.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَى حَدِيثِهِمَا
