وَلَوْ أَنَّ لِكُلِّ نَفْسٍۢ ظَلَمَتْ مَا فِى ٱلْأَرْضِ لَٱفْتَدَتْ بِهِۦ ۗ وَأَسَرُّوا۟ ٱلنَّدَامَةَ لَمَّا رَأَوُا۟ ٱلْعَذَابَ ۖ وَقُضِىَ بَيْنَهُم بِٱلْقِسْطِ ۚ وَهُمْ لَا يُظْلَمُونَ
And if each soul that doeth wrong had all that is in the earth it would seek to ransom itself therewith; and they will feel remorse within them, when they see the doom. But it hath been judged between them fairly and they are not wronged.
