وَمَنْ خَفَّتْ مَوَازِينُهُ فَأُوْلَـئِكَ الَّذِينَ خَسِرُواْ أَنفُسَهُم بِمَا كَانُواْ بِآيَاتِنَا يِظْلِمُونَ
[7:9]
And as for him whose measure (of good deeds) is light those are they who have made their souls suffer loss because they disbelieved in Our communications.
Those whose scale will be light, will be their souls in perdition, for that they wrongfully treated Our signs.
And as for those whose scale is light: those are they who lose their souls because they used to wrong Our revelations.
