Guessing at random (- about them) some say, `(They were) three, their dog being the fourth,' while others say, `(They were) five and their dog being the sixth.' Yet there are others who say, `(They were) seven and their dog being the eighth.' Say, `My Lord knows best their real number. None knows them except a few.' So do not argue about them save with arguing on known premise (which is) overpowering and seek no legal order concerning them from anyone of them, (from those who make random guesses).
