سورة المؤمنون

Imam Sadiq (peace be upon him): An unbeliever asked the Imam: "Are deeds not weighed?" The Imam answered: "No, deeds are not of the nature of matter; rather, they are attributes of what [people] have done. The one who needs to weigh something is the one who does not know the weight and quantity, the lightness and heaviness of it, whereas nothing is hidden from Allah the Exalted." He asked: "Then what is the meaning of the mizan (balance)?" The Imam answered: "Justice." He asked: "What is the meaning of this verse: فَمَنْ ثَقُلَتْ مَوازِینُهُ [Then as for him whose good deeds are preponderant]?" The Imam said: "It means whoever's good deeds are more [than his sins]."

Imam Baqir (peace be upon him): This verse was revealed concerning us, the Ahl al-Bayt (peace be upon them).

Ali ibn Ibrahim (may Allah have mercy on him): فَمَنْ ثَقُلَتْ مَوازِینُهُ [Then as for him whose good deeds are preponderant] — meaning the scale of his deeds becomes heavy with good deeds; فَأُولئِکَ هُمُ الْمُفْلِحُونَ [these are the successful]. وَ مَنْ خَفَّتْ مَوازِینُهُ [And as for him whose good deeds are light] — meaning the pan of his good deeds is light; so they are those who have lost the capital of their own existence and will abide forever in Hell.

Imam Ali (peace be upon him): The meaning of فَمَنْ ثَقُلَتْ مَوازِینُهُ وَ مَنْ خَفَّتْ مَوازِینُهُ [Then as for him whose good deeds are preponderant, and as for him whose good deeds are light] is the fewness of the reckoning.

Imam Ali (peace be upon him): فَمَنْ ثَقُلَتْ مَوازِینُهُ وَ مَنْ خَفَّتْ مَوازِینُهُ [Then as for him whose good deeds are preponderant, and as for him whose good deeds are light] is the reckoning and weighing of good deeds and bad deeds; good deeds are the heaviness of the balance and bad deeds are the lightness of the balance.
