And you would have thought them awake, while they were asleep. And We turned them on their right and on their left sides, and their dog stretching forth his two forelegs at the entrance [of the Cave or in the space near to the entrance of the Cave (as a guard at the gate)]. Had you looked at them, you would certainly have turned back from them in flight, and would certainly have been filled with awe of them. 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 if they should come upon us, they will stone us to death or force us to revert to their faith whereafter we shall 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 Some will say concerning them: "They were three and their dog, the fourth"; and some will say: "They were five, and their dog, the sixth" -- all this being merely guesswork; and still others will say: "They were seven, and their dog, the eighth." Say: "My Lord knows their number best. Only a few know their correct number. So do not dispute concerning their number, but stick to what is evident, and do not question anyone about them." 22
