As to those who reject Faith, it is the same to them whether you warn them or do not warn them. They will not believe.

And, there are some people who say, "We believe in God and the Last Day," and they are not at all believers.

They desire to deceive God and those who believe.
They deceive only themselves, and they do not perceive.

O Children of Israel!
Call to mind My favor which I bestowed on you and be faithful to your Covenant with Me, I will fulfill My Covenant with you.
