لِلَّذِينَ ٱسْتَجَابُوا۟ لِرَبِّهِمُ ٱلْحُسْنَىٰ ۚ وَٱلَّذِينَ لَمْ يَسْتَجِيبُوا۟ لَهُۥ لَوْ أَنَّ لَهُم مَّا فِى ٱلْأَرْضِ جَمِيعًۭا وَمِثْلَهُۥ مَعَهُۥ لَٱفْتَدَوْا۟ بِهِۦٓ ۚ أُو۟لَٰٓئِكَ لَهُمْ سُوٓءُ ٱلْحِسَابِ وَمَأْوَىٰهُمْ جَهَنَّمُ ۖ وَبِئْسَ ٱلْمِهَادُ
For those who answered Allah's call is bliss; and for those who answered not His call, if they had all that is in the earth, and therewith the like thereof, they would proffer it as ransom. Such will have a woeful reckoning, and their habitation will be hell, a dire abode.
Surah Ar-Ra'd(13:18)
