Thou wouldst have deemed them awake, whilst they were asleep, and We turned them on their right and on their left sides: their dog stretching forth his two fore-legs on the threshold: if thou hadst come up on to them, thou wouldst have certainly turned back from them in flight, and wouldst certainly have been filled with terror of them. 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 come to know of you, they will stone you (to death or abuse and harm you) or turn you back to their religion, and in that case you will never be successful." 20 And so We made them (the unbelievers) stumble upon them, so that they might know that the promise of Allah is true and that there is no doubt about the Hour. They argued among themselves over their affair, then (the unbelievers) said: 'Build a building over them (their remains). Their Lord knows best who they were. 'But those who prevailed over the matter said; 'We will build around them a Mosque' 21 Some will say: 'They were three; their dog was the fourth' Others, guessing at the Unseen, will say: 'They were five and their dog was the sixth' And yet others: 'Seven; their dog was the eighth' Say: 'My Lord knows best their number. Except for a few none know their number' Therefore, do not dispute with them except in outward disputation, and do not ask any of them concerning them. 22
