﴿ 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!”

(Thus Allah made them taste humiliation in the life of the world) He made them taste the chastisement of the life of this world, (and verily the doom of the Hereafter will be greater) than the chastisement they incurred in the life of this world (if they did but know) but they do not know.
