And mention when God took a solemn promise from the Prophets: Whatever I gave you of the Book and wisdom, again, if a Messenger drew near you with that which establishes as true what is with you, you will believe in him and you will help him. He said: Are you in accord? And will you take on My severe test? They said: We are in accord. He said: Then, bear witness and I am with you among the ones who bear witness.
