Al-Qalam 68:44

Fatharnee waman yukaththibubihatha alhadeethi sanastadrijuhum min haythula yaAAlamoon

So leave Me, [O Muḥammad], with [the matter of] whoever denies this statement [i.e., the Qur’ān]. We will progressively lead them [to punishment] from where they do not know.

So, leave Me alone with those who reject this discourse. We will draw them on little by little (towards Hell) from a way they do not know.
