Characteristics of the Day of Judgment, Paradise, and Hell
Ṣaḥīḥ Muslim 7089
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
inna-Llāh lā yaẓlimu muʾminan ḥasanatan yuʿṭā bihā fī ad-dunyā wayujzā bihā fī al-ākhirah wa-ammā al-kāfiru fayuṭʿamu biḥasanāti mā ʿamila bihā lillāh fī ad-dunyā ḥattā idhā afḍā ilā al-ākhirah lam takun lah ḥasanatun yujzā bihā

The full narration
Anas b. Malik reported that Allah's Messenger (ﷺ) said: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
