﴿ لِيَكْفُرُوا۟ بِمَآ ءَاتَيْنَٰهُمْ ۚ فَتَمَتَّعُوا۟ ۖ فَسَوْفَ تَعْلَمُونَ ﴾

“[as if] to prove their ingratitude for all that We have granted them! Enjoy, then, your [brief] life: but in time you will come to know [the truth]!”

in order to deny that which We have given them. So enjoy, for soon you shall know, the evil consequence of that belief for them. Or [it is that]: you shall know at the manifestation of [His] unity that nothing other than God has the power of effect over anything.
