One would think them (the youths) awake while, in fact, they were sleeping. We turned their bodies from right to left and their dog stretched its front legs on the ground. Had one looked them over, he would have run away from them in terror. 18 And similarly We awakened them so that they may enquire about each other; a speaker among them said, “How long have you stayed here?” Some among them said, “We have stayed a day or part of a day”; the others said, “Your Lord well knows how long you have stayed; therefore send one of you to the city with this silver coin – he may then check which food available there is purer, in order to bring some of it for you to eat – and he must be courteous and not inform anyone about you.” 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 in like manner We disclosed them (to the people of the city) that they might know that the promise of Allah is true, and that, as for the Hour, there is no doubt concerning it. When (the people of the city) disputed of their case among themselves, they said: Build over them a building; their Lord knoweth best concerning them. Those who won their point said: We verily shall build a place of worship over them. 21 Some will say: "They were three, and their dog was the fourth;" and some will also say: "They were five and their dog was the sixth," -- guessing in the dark. And some will even say: "They were seven, and their dog the eighth." Say: "My Lord alone knows best their number; none but only a few know of them." So do not argue about it with them but lightly, and do not enquire about them from any one of them. 22
