﴿ فَأَذَاقَهُمُ ٱللَّهُ ٱلْخِزْىَ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَلَعَذَابُ ٱلْءَاخِرَةِ أَكْبَرُ ۚ لَوْ كَانُوا۟ يَعْلَمُونَ ﴾

“and thus God let them taste ignominy [even] in the life of this world. Yet [how] much greater will be the [sinners’] suffering in the life to come - if they [who now deny the truth] but knew it!”

So God made them taste disgrace abasement and humiliation in the way of being transformed into swine and being killed and otherwise in the life of this world. And the chastisement of the Hereafter will surely be greater had they that is the deniers known the nature of the chastisement thereof they would not have denied.
