And thou wouldst have thought that they were awake, whereas they lay asleep. And We caused them to turn over repeatedly, now to the right, now to the left; and their dog [lay] on the threshold, its forepaws outstretched. Hadst thou come upon them [unprepared,] thou wouldst surely have turned away from them in flight, and wouldst surely have been filled with awe 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 If they should get knowledge of you they will stone you, or restore you to their creed, then you will not prosper ever. 20 And this is how We made them known for people to know that the promise of Allah is true and that there is no doubt concerning the Last Day; when the people began disputing among themselves regarding them, they said, “Construct a building over their cave”; their Lord well knows them; those who dominated in this matter said, “We promise we will build a mosque over them.” 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
