﴿ ذَٰلِكَ جَزَآؤُهُمْ جَهَنَّمُ بِمَا كَفَرُوا۟ وَٱتَّخَذُوٓا۟ ءَايَٰتِى وَرُسُلِى هُزُوًا ﴾

“That will be their recompense - [their] hell -for having denied the truth and made My messages and My apostles a target of their mockery.”

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.
