They will say: They were three, the fourth of them being their dog. And they will say: They were five, the sixth of them being their dog, guessing at the unseen. And they will say: They were seven, the eighth of them being their dog. Say: My Lord is greater in knowledge of their amount. No one knows them but a few, so altercate not about them but with a manifest argumentation and ask not for advice about them of anyone of them.
