وَمَنْ يَعْمَلْ مِثْقَالَ ذَرَّةٍ شَرًّا يَرَهُ
Whoever does an atom's weight of evil shall see it. (al-Zalzalah 99:8)
وَمَنْ يَعْمَلْ سُوءًا يُجْزَ بِهِ
Whoever does evil shall be requited for it. (al-Nisāʾ 4:123)
These texts establish the gravity of accountability. They must be read with the texts of expiation and pardon, while distinguishing recording and showing a deed from inevitable and permanent punishment.
Recognition of a deed in the final account does not by itself entail that its perpetrator must suffer eternal punishment.
