Surah Al-Kahf 18:106

ذَٰلِكَ جَزَآؤُهُمْ جَهَنَّمُ بِمَا كَفَرُوا۟ وَٱتَّخَذُوٓا۟ ءَايَـٰتِى وَرُسُلِى هُزُوًا

That is their recompense - Hell - for what they denied and [because] they took My signs and My messengers in ridicule.

Translation: Saheeh International

Tafsir

That namely the matter which I God have mentioned concerning the failure of their deeds and so on dhālika ‘that’ constitutes the subject is their requital — Hell — because they disbelieved and took My signs and My messengers in mockery that is to say taking both of them as something to be derided.
