This is Allah's guidance, He guides thereby whom He pleases of His servants; and if they had set up others (with Him), certainly what they did would have become ineffectual for them.

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.
