Anas bin Malik reported that Allah’s Messenger (ﷺ) said:Verily, Allah does not treat a mu’min unjustly in regard to his good deeds. He would confer upon him (His blessing) in this world and would give him reward in the Hereafter. And as regards a disbeliever, he would be made to taste the reward (of good deeds in this world) what he has done for himself so much that in the Hereafter, he would find no good deeds for which he should be rewarded.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، – وَاللَّفْظُ لِزُهَيْرٍ – قَالاَ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا هَمَّامُ بْنُ يَحْيَى، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم “ 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 ” .
