And God has made for you shade from what He has created, and He has made from the mountains a refuge for you, and He has made for you garments which protect you from the heat, and garments which protect you from attack. It is such that He completes His blessings upon you, that perhaps you may submit.

So if they turn away, then you are only required to deliver clearly.

They recognize the blessings of God, then they deny them. And most of them are rejecters.

And the Day We send from every nation a witness, then those who have rejected will not be given leave, nor will they be allowed to repent.

And then those who were wicked will see the retribution; it will not be lightened for them, nor will they be given respite.
