﴿ مَن جَآءَ بِٱلْحَسَنَةِ فَلَهُۥ عَشْرُ أَمْثَالِهَا ۖ وَمَن جَآءَ بِٱلسَّيِّئَةِ فَلَا يُجْزَىٰٓ إِلَّا مِثْلَهَا وَهُمْ لَا يُظْلَمُونَ ﴾

“Whoever shall come [before God] with a good deed will gain ten times the like thereof; but whoever shall come with an evil deed will be requited with no more than the like thereof; and none shall be wronged.”

(Whoso bringeth a good deed) while confessing Allah's divine Oneness (will receive tenfold the like thereof, while whoso bringeth an ill deed) while ascribing partners to Allah (will be awarded but the like thereof) i.e. the Fire; (and they will not be wronged) their good deeds will not be diminished nor will their bad deeds be increased.
