Saba' - 34:17

ذَلِكَ جَزَيْنَاهُم بِمَا كَفَرُوا وَهَلْ نُجَازِي إِلَّا الْكَفُورَ
[34:17]
This We requited them with because they disbelieved; and We do not punish any but the ungrateful.
That was the Requital We gave them because they ungratefully rejected Faith: and never do We give (such) requital except to such as are ungrateful rejecters.
This We awarded them because of their ingratitude. Punish We ever any save the ingrates?
