Al-A'raf 7:8

وَٱلْوَزْنُ يَوْمَئِذٍ ٱلْحَقُّ ۚ فَمَن ثَقُلَتْ مَوَٰزِينُهُۥ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ

Wal-waznu yawma-idhin l-ḥaqu faman thaqulat mawāzīnuhu fa-ulāika humu l-muf'liḥūna

And the weighing [of deeds] that Day will be the truth. So those whose scales are heavy - it is they who will be the successful.
