إِنَّ ٱلَّذِينَ كَفَرُوا۟ لَوْ أَنَّ لَهُم مَّا فِى ٱلْأَرْضِ جَمِيعًۭا وَمِثْلَهُۥ مَعَهُۥ لِيَفْتَدُوا۟ بِهِۦ مِنْ عَذَابِ يَوْمِ ٱلْقِيَٰمَةِ مَا تُقُبِّلَ مِنْهُمْ ۖ وَلَهُمْ عَذَابٌ أَلِيمٌۭ
As for those who disbelieve, lo! if all that is in the earth were theirs, and as much again therewith, to ransom them from the doom on the Day of Resurrection, it would not be accepted from them. Theirs will be a painful doom.
Surah Al-Maaida(5:36)
