On seeing them you would fancy them to be awake though they were asleep; and We caused them to turn their sides to their right and to their left, and their dog sat stretching out its forelegs on the threshold of the Cave. Had you looked upon them you would have certainly fled away from them, their sight filling you with terror. 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 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 Thus did We inform the people about them that they may know the promise of God is true, and there is no doubt that the Hour will come. As they were arguing among themselves as to what should be done with them, (some) said: "Erect a monument over them. Their Lord is best cognisant of them." Those who prevailed, said: "We shall build a place of worship over their (sepulchre)." 21 Anon they will say: they were three the fourth of them their dog. And they will say: they were five, the sixth of them their dog - guessing at the unknown - and they will say: they were seven, the eighth of them their dog. Say thou: my Lord is the Best Knower of their number; there knew them only a few; so debate thou not regarding them except an outward debating, and ask not regarding them anyone of them. 22
