And those whose scales are light - they are the ones who will lose themselves for what injustice they were doing toward Our verses.
The Saheeh International Quran Translation
وَمَنْ خَفَّتْ مَوَٰزِينُهُۥ فَأُو۟لَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُم بِمَا كَانُوا۟ بِـَٔايَٰتِنَا يَظْلِمُونَAnd those whose scales are light - they are the ones who will lose themselves for what injustice they were doing toward Our verses.
