﴿ أُو۟لَٰٓئِكَ ٱلَّذِينَ ٱشْتَرَوُا۟ ٱلْحَيَوٰةَ ٱلدُّنْيَا بِٱلْءَاخِرَةِ ۖ فَلَا يُخَفَّفُ عَنْهُمُ ٱلْعَذَابُ وَلَا هُمْ يُنصَرُونَ ﴾

“All who buy the life of this world at the price of the life to come - their suffering shall not be lightened, nor shall they be succoured!”

This verse explains why the Jews will have to undergo such a severe punishment. They have been disobeying Allah in order to satisfy their desires and to enjoy worldly pleasures; they have also sacrificed for these things their salvation in the other world. Their sin being so great, Allah will not reduce or mollify their punishment, nor will He allow anyone to intercede on their behalf.
