﴿فَمَنْ ثَقُلَتْ مَوَازِينُهُ فَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ﴾
“Those whose scales are heavy—it is they who will succeed.” (al-Aʿrāf 7:8)
Heaviness concerns the value and acceptance of deeds; lightness is associated with loss. An outwardly small act may be weighty through sincerity, while an impressive-looking deed may be very different in reality.
The final weighing cannot therefore be reduced to a simple count of actions. Outward conduct, intention, acceptance, and divine justice must not be confined to human estimates.
