Concise Quran Commentary
By this punishment Allah made them taste humiliation, disgrace and shame in the worldly life. The punishment of the Hereafter that awaits them is worse and more severe if they only knew.
فَأَذَاقَهُمُ ٱللَّهُ ٱلْخِزْىَ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا ۖ وَلَعَذَابُ ٱلْـَٔاخِرَةِ أَكْبَرُ ۚ لَوْ كَانُوا۟ يَعْلَمُونَ
Therefore Allah gave them a taste of disgrace in the life of this world, but the punishment of the Hereafter will be far greater, if only they knew.
