Surah Al-Mu'minun, ayah 103

وَمَنۡ خَفَّتۡ مَوَٰزِينُهُۥ فَأُوْلَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فِي جَهَنَّمَ خَٰلِدُونَ ١٠٣

Waman khaffat mawāzīnuhū fa ulā'ikal-ladhīna khasirū anfusahum fī jahannama khālidūn

But those whose scales are light - those are the ones who have lost their souls, [being] in Hell, abiding eternally.
