مَّن كَانَ يُرِيدُ ٱلْعَاجِلَةَ عَجَّلْنَا لَهُۥ فِيهَا مَا نَشَآءُ لِمَن نُّرِيدُ ثُمَّ جَعَلْنَا لَهُۥ جَهَنَّمَ يَصْلَىٰهَا مَذْمُومًۭا مَّدْحُورًۭا
Whoso desireth that (life) which hasteneth away, We hasten for him therein what We will for whom We please. And afterward We have appointed for him hell; he will endure the heat thereof, condemned, rejected.
