You would have thought they were awake, though they lay asleep. We turned them over, to the right and the left, while their dog lay at the cave's entrance with legs outstretched. Had you looked down and seen them, you would have surely turned your back and fled in terror. 18 Likewise, We awakened them (from their long deep sleep) that they might question one another. A speaker from among them said: "How long have you stayed (here)?" They said: "We have stayed (perhaps) a day or part of a day." They said: "Your Lord (Alone) knows best how long you have stayed (here). So send one of you with this silver coin of yours to the town, and let him find out which is the good lawful food, and bring some of that to you. And let him be careful and let no man know 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 similarly, We caused them to be found that they [who found them] would know that the promise of Allah is truth and that of the Hour there is no doubt. [That was] when they disputed among themselves about their affair and [then] said, "Construct over them a structure. Their Lord is most knowing about them." Said those who prevailed in the matter, "We will surely take [for ourselves] over them a masjid." 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
