And you might think them awake while they were asleep and We turned them about to the right and to the left, while their dog (lay) outstretching its paws at the entrance; if you looked at them you would certainly turn back from them in flight, and you would certainly be filled with awe because of them. 18 In the course of time, We raised them up again so that they might question one another. One of them asked, "How long have you stayed [here]?" They said, "We have stayed a day, or part of a day." But others said, "Your Lord knows best how long you have stayed here. Let one of you go then with these silver coins to the town, and let him find out what food is purest there, and bring you back a supply of it. Let him conduct himself with caution and not disclose your whereabouts to anyone: 19 Indeed, if they come to know of you, they will stone you or return you to their religion. And never would you succeed, then - ever." 20 Thus did We make their case known to the people of the city so that they might know that Allah's promise is true, and that there is absolutely no doubt that the Hour will come to pass. But instead of giving thought to this, they disputed with one another concerning the People of the Cave, some saying: "Build a wall over them. Their Lord alone knows best about them." But those who prevailed over their affairs said: "We shall build a place of worship over them." 21 (Some) say they were three, the dog being the fourth among them; (others) say they were five, the dog being the sixth, guessing at the unseen; (yet others) say they were seven, the dog being the eighth. Say (O Muhammad SAW): "My Lord knows best their number; none knows them but a few." So debate not (about their number, etc.) except with the clear proof (which We have revealed to you). And consult not any of them (people of the Scripture, Jews and Christians) about (the affair of) the people of the Cave. 22
