But if they dispute with you, say: I have submitted myself entirely to Allah and (so) every one who follows me; and say to those who have been given the Book and the unlearned people: Do you submit yourselves? So if they submit then indeed they follow the right way; and if they turn back, then upon you is only the delivery of the message and Allah sees the servants.

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.
