Surah Al-Mu'minun — Ayah 102 (23:102)
فَمَن ثَقُلَتۡ مَوَٰزِينُهُۥ فَأُوْلَٰٓئِكَ هُمُ ٱلۡمُفۡلِحُونَ ١٠٢
English translation (Saheeh International)
And those whose scales are heavy [with good deeds] - it is they who are the successful.
Brief commentary
So whoever’s scales are heavy because of his good actions outweighing his bad actions, those are the successful ones, by attaining their objective and being saved from their fears.
