And thou wouldst have thought that they were awake, whereas they lay asleep. And We caused them to turn over repeatedly, now to the right, now to the left; and their dog [lay] on the threshold, its forepaws outstretched. Hadst thou come upon them [unprepared,] thou wouldst surely have turned away from them in flight, and wouldst surely have been filled with awe of them. 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, if they appear in front of you, they will stone you to death or restore you to their religion. Then you will never prosper' 20 And thus did We make (men) to get knowledge of them that they might know that Allah's promise is true and that as for the hour there is no doubt about it. When they disputed among themselves about their affair and said: Erect an edifice over them-- their Lord best knows them. Those who prevailed in their affair said: We will certainly raise a masjid over them. 21 [And in times to come] some will say: "[They were] three, the fourth of them being their dog," while others will say: "Five, with their dog as the sixth of them" - idly guessing at something of which they can have no knowledge - and [so on, until] some will say: "[They were] seven, the eighth of them being their dog." Say: "My Sustainer knows best how many they were. None but a few have any [real] knowledge of them. Hence, do not argue about them otherwise than by way of an obvious argument, and do not ask any of those [story-tellers] to enlighten thee about them." 22
