﴿ ذَٰلِكَ بِأَنَّهُمُ ٱسْتَحَبُّوا۟ ٱلْحَيَوٰةَ ٱلدُّنْيَا عَلَى ٱلْءَاخِرَةِ وَأَنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَٰفِرِينَ ﴾

“all this, because they hold this world's life in greater esteem than the life to come, and because God does not bestow His guidance upon people who deny the truth.”

(That) torment (is because they have chosen the life of the world) they preferred this worldly life (rather than the Hereafter) and chose disbelief instead of faith, (and because Allah guideth not) to His religion nor save them from His torment (the disbelieving folk) who do not deserve it.
