And you may think they are awake, whereas they are asleep; and We turn them over to the right and the left – and their dog is on the threshold of the cave, with its paws outstretched; O listener, were you to look at them closely, you would turn back running away from them, and be filled with their dread. 18 Even so We roused them that they may question one another. One of them asked: "How long have you stayed here?" They said: "A day or less than a day." "Your Lord knows best," they said, "how long you have stayed. So send one of you to the town with this money of yours to look for wholesome food and bring it for you; but he should be careful not to let your presence known. 19 for, behold, if they should come to know of you, they might stone you to death or force you back to their faith - in which case you would never attain to any good!" 20 Thus did We make their case known to the people, that they might know that the promise of Allah is true, and that there can be no doubt about the Hour of Judgment. Behold, they dispute among themselves as to their affair. (Some) said, "Construct a building over them": Their Lord knows best about them: those who prevailed over their affair said, "Let us surely build a place of worship over them." 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
