(As for) those, their portion of the Book shall reach them, until when Our apostles 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

Or have they set up with Allah associates who have created creation like His, so that what is created became confused to them? Say: Allah is the Creator of all things, and He is the One, the Supreme.
