And when Allah made a covenant through the prophets: Certainly what I have given you of Book and wisdom-- then an messenger comes to you verifying that which is with you, you must believe in him, and you must aid him. He said: Do you affirm and accept My compact in this (matter)? They said: We do affirm. He said: Then bear witness, and I (too) am of the bearers of witness with you.

Who is then more unjust than he who forges a lie against Allah or rejects His communications? (As for) those, their portion of the Book shall reach them, until when Our messengers come to them causing them to die, they shall say: Where is that which you used to call upon besides Allah? They would say: They are gone away from us; and they shall bear witness against themselves that they were unbelievers

And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book.
