And certainly We raised in every nation a messenger saying: Serve Allah and shun the Shaitan. So there were some of them whom Allah guided and there were others against whom error was due; therefore travel in the land, then see what was the end of the rejecters.

And that which We have revealed to you of the Book, that is the truth verifying that which is before it; most surely with respect to His servants Allah is Aware, Seeing.

Surely We have revealed to you the Book with the truth, therefore serve Allah, being sincere to Him in obedience.
