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 We have revealed to you the Book with the truth, verifying what is before it of the Book and a guardian over it, therefore judge between them by what Allah has revealed, and do not follow their low desires (to turn away) from the truth that has come to you; for every one of you did We appoint a law and a way, and if Allah had pleased He would have made you (all) a single people, but that He might try you in what He gave you, therefore strive with one another to hasten to virtuous deeds; to Allah is your return, of all (of you), so He will let you know that in which you differed;
