﴿ لِيُكَفِّرَ ٱللَّهُ عَنْهُمْ أَسْوَأَ ٱلَّذِى عَمِلُوا۟ وَيَجْزِيَهُمْ أَجْرَهُم بِأَحْسَنِ ٱلَّذِى كَانُوا۟ يَعْمَلُونَ ﴾

“And to this end, God will efface from their record the worst that they ever did, and give them their reward in accordance with the best that they were doing [in life].”

(That Allah will remit from them the worst of what they did) the vilest of their works, (and will pay them for reward the best they used to do) of good.
