On seeing them you would fancy them to be awake though they were asleep; and We caused them to turn their sides to their right and to their left, and their dog sat stretching out its forelegs on the threshold of the Cave. Had you looked upon them you would have certainly fled away from them, their sight filling you with terror. 18 And similarly, We awakened them that they might question one another. Said a speaker from among them, "How long have you remained [here]?" They said, "We have remained a day or part of a day." They said, "Your Lord is most knowing of how long you remained. So send one of you with this silver coin of yours to the city and let him look to which is the best of food and bring you provision from it and let him be cautious. And let no one be 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 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
