إِنَّ ٱلَّذِينَ كَفَرُوا۟ وَمَاتُوا۟ وَهُمْ كُفَّارٌۭ فَلَن يُقْبَلَ مِنْ أَحَدِهِم مِّلْءُ ٱلْأَرْضِ ذَهَبًۭا وَلَوِ ٱفْتَدَىٰ بِهِۦٓ ۗ أُو۟لَٰٓئِكَ لَهُمْ عَذَابٌ أَلِيمٌۭ وَمَا لَهُم مِّن نَّٰصِرِينَ
Lo! those who disbelieve, and die in disbelief, the (whole) earth full of gold would not be accepted from such an one if it were offered as a ransom (for his soul). Theirs will be a painful doom and they will have no helpers.
