Eternal punishment in the Afterlife

وَٱلَّذِينَ كَفَرُوا۟ لَهُمْ نَارُ جَهَنَّمَ لَا يُقْضَىٰ عَلَيْهِمْ فَيَمُوتُوا۟ وَلَا يُخَفَّفُ عَنْهُم مِّنْ عَذَابِهَا ۚ كَذَٰلِكَ نَجْزِى كُلَّ كَفُورٍ

And for those who disbelieve will be the fire of Hell. [Death] is not decreed for them so they may die, nor will its torment be lightened for them. Thus do We recompense every ungrateful one.
