Surah Al-Mu'minun — Ayah 103 (23:103)
وَمَنۡ خَفَّتۡ مَوَٰزِينُهُۥ فَأُوْلَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فِي جَهَنَّمَ خَٰلِدُونَ ١٠٣
English translation (Saheeh International)
But those whose scales are light - those are the ones who have lost their souls, [being] in Hell, abiding eternally.
Brief commentary
And whoever’s scales are light because of his bad deeds outweighing his good deeds, those are the ones who have wasted themselves by doing that which is harmful to them, i.e., disbelief and sins, and leaving faith and good actions that were beneficial for them. They will be in the fire of hell forever and will not come out of it.
