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 on the day when We will raise up in every people a witness against them from among themselves, and bring you as a witness against these-- and We have revealed the Book to you explaining clearly everything, and a guidance and mercy and good news for those who submit.
