You might have thought them awake, though they were sleeping. We turned them about to the right and to the left, while their dog stretched its paws at the entrance. Had you seen them you would surely have become filled with terror and turned your back on them in flight. 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, behold, if they should come to know of you, they might stone you to death or force you back to their faith - in which case you would never attain to any good!" 20 AND IN THIS way have We drawn [people's] attention to their story, so that they might know - whenever they debate among themselves as to what happened to those [Men of the Cave] that God's promise [of resurrection] is true, and that there can be no doubt as to [the coming of] the Last Hour. And so, some [people] said: "Erect a building in their memory; God knows best what happened to them." Said they whose opinion prevailed in the end: "Indeed, we must surely raise a house of worship in their memory!" 21 (With regard to the number of the youths) some say, "There were three and the dog was the fourth one," Others say, "There were five and the dog was the sixth one." In reality, they are just feeling around in the dark. Still some of them say, "There were seven and the dog was the eighth one." (Muhammad), say, "My Lord has the best knowledge of their number. You know very little about it." Do not insist on arguing with them, but merely tell them the story as it has been revealed to you and do not ask anyone about them. 22
