لِيَكْفُرُواْ بِمَا آتَيْنَاهُمْ فَتَمَتَّعُواْ فَسَوْفَ تَعْلَمُونَ
[16:55]
So that they be ungrateful for what We have given them; then enjoy yourselves; for soon will you know
(As if) to show their ingratitude for the favours we have bestowed on them! then enjoy (your brief day): but soon will ye know (your folly)!
So as to deny that which We have given them. Then enjoy life (while ye may), for ye will come to know.
