لِيَجْزِيَ الَّذِينَ أَسَاءُوا بِمَا عَمِلُوا وَيَجْزِيَ الَّذِينَ أَحْسَنُوا بِالْحُسْنَى
So that those who did evil may be repaid for what they did, and those who did good may be given the finest reward. (al-Najm 53:31)
Isāʾah denotes wrongdoing, whereas iḥsān denotes doing good. Their recompenses are distinct rather than interchangeable.
