﴿ ذَٰلِكَ جَزَيْنَٰهُم بِمَا كَفَرُوا۟ ۖ وَهَلْ نُجَٰزِىٓ إِلَّا ٱلْكَفُورَ ﴾

“thus We requited them for their having denied the truth. But do We ever requite [thus] any but the utterly ingrate?”

That replacement of what they had is what We requited them with for their ingratitude and is anyone but the ingrate ever so requited? read hal yujāzā illā’l-kafūru; or read as hal nujāzī illā’l-kafūra ‘Would We requite anyone but the ingrate?’ in other words it is only the like of such who is called to account.
