Surah Al-Qasas 28:84

مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ خَيْرٌ مِّنْهَا ۖ وَمَن جَآءَ بِٱلسَّيِّئَةِ فَلَا يُجْزَى ٱلَّذِينَ عَمِلُوا۟ ٱلسَّيِّـَٔاتِ إِلَّا مَا كَانُوا۟ يَعْمَلُونَ

Whoever comes [on the Day of Judgement] with a good deed will have better than it; and whoever comes with an evil deed - then those who did evil deeds will not be recompensed except [as much as] what they used to do.

Translation: Saheeh International
