They will say, ‘There were three of them, their dog being the fourth.’ They will say, ‘There were five of them, their dog being the sixth,’ guessing at the Unseen. And they will say, ‘There were seven of them, their dog being the eighth.’ Say: ‘My Lord knows best their number. Those who know about them are very few.’ So do not enter into any argument concerning them, except in relation to what is clearly known. And do not seek the opinion of any of them regarding them.
