الاعراف — Al-A'raf Ayat 8

وَالْوَزْنُ يَوْمَىِٕذِ ِۨالْحَقُّۚ فَمَنْ ثَقُلَتْ مَوَازِيْنُهٗ فَاُولٰۤىِٕكَ هُمُ الْمُفْلِحُوْنَ

Wal-waznu yauma'iżinil-ḥaqq(u), faman ṡaqulat mawāzīnuhū fa ulā'ika humul-mufliḥūn(a).

"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."
