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 And even so We raised them up again that they might question one another. One of them said, 'How long have you tarried?' They said, 'We have tarried a day, or part of a day.' They said, 'Your Lord knows very well how long you have tarried. Now send one of you forth with this silver to the city, and let him look for which of them has purest food, and bring you provision thereof; let him be courteous, and apprise no man of you. 19 “Indeed if they come to know about you, they will stone you or turn you back to their religion – and if so, you will never prosper.” 20 Thus We disclosed things to them so that they might know that God's promise was true and there was no doubt about the Hour [Judgement Day]. The people argued about them among themselves. They said, "Build a monument over them. Their Lord knows best concerning them." Those who prevailed in their affair said, "Let us surely build a place of worship 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
