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 And likewise we raised them up that they might question among themselves; there spake a speaker from amongst them: how long have ye tarried? They said we have tarried a day or part of a day. They said, your Lord knoweth best how long ye have tarried; now send one of you with this your money unto the city and let him see which food is purest there, and let him bring you a provision thereof, and let him be circumspect, and let him by no means discover you 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 We caused their story to become public so that people would know that God's promise was true and that there is no doubt about the coming of the Day of Judgment. They started to argue with each other about the matter (Resurrection) and some of them said, "Let us establish a building at the youths' sleeping place (to hide them). Their Lord knew best their intentions about them. The majority prevailed in their suggestion of the establishment of a mosque in that place. 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
