﴿ وَأَنَّ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ أَعْتَدْنَا لَهُمْ عَذَابًا أَلِيمًۭا ﴾

“and [it announces, too,] that We have readied grievous suffering for those who will not believe in the life to come.”

And it this Qur’ān informs that those who do not believe in the Hereafter We have prepared for them a painful chastisement namely the Fire.
