الْيَوْمَ تُجْزَىٰ كُلُّ نَفْسٍ بِمَا كَسَبَتْ لَا ظُلْمَ الْيَوْمَ إِنَّ اللَّهَ سَرِيعُ الْحِسَابِ
Today every soul will be repaid for what it earned; there will be no injustice today. Allah is swift in reckoning. (Ghāfir 40:17)
There is no injustice today affirms the justice of the account. Nobody's deeds will be dealt with through unfairness or wrongful attribution.
