And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them. 18 And so, [in the course of time,] We awakened them; and they began to ask one another [as to what had happened to them]. One of them asked: "How long have you remained thus?" [The others] answered: "We have remained thus a day, or part of a day." Said they [who were endowed with deeper insight]: "Your Sustainer knows best how long you have thus remained. Let, then, one of you go with these silver coins to the town, and let him find out what food is purest there, and bring you thereof [some] provisions. But let him behave with great care and by no means make anyone aware of you: 19 For they, if they should come to know of you, will stone you or turn you back to their religion; then ye will never prosper. 20 And so We made them (the unbelievers) stumble upon them, so that they might know that the promise of Allah is true and that there is no doubt about the Hour. They argued among themselves over their affair, then (the unbelievers) said: 'Build a building over them (their remains). Their Lord knows best who they were. 'But those who prevailed over the matter said; 'We will build around them a Mosque' 21 Some will say: 'They were three; their dog was the fourth' Others, guessing at the Unseen, will say: 'They were five and their dog was the sixth' And yet others: 'Seven; their dog was the eighth' Say: 'My Lord knows best their number. Except for a few none know their number' Therefore, do not dispute with them except in outward disputation, and do not ask any of them concerning them. 22
