﴿ وَإِنَّ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ عَنِ ٱلصِّرَٰطِ لَنَٰكِبُونَ ﴾

“but, behold, those who will not believe in the life to come are bound to deviate from that way.”

And truly those who do not believe in the Hereafter in resurrection reward and punishment deviate swerve away from the path that is the route to salvation.
