You would have thought they were awake, though they lay asleep. We turned them over, to the right and the left, while their dog lay at the cave's entrance with legs outstretched. Had you looked down and seen them, you would have surely turned your back and fled in terror. 18 We roused them from their sleep so that they would question each other about their stay in the cave. One of them said, "How long do you think we have stayed here?" They replied, "A day or part of a day." They added, " Your Lord knows better how long we have stayed here. Let us send one of us with this money to the city to get some pure food so that we might eat. He should be careful so that no one will know about us. If they were to recognize us, 19 for if they find you out, they will stone you to death, or force you back into their faith. In that case you would never prosper." 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 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
