And you may think they are awake, whereas they are asleep; and We turn them over to the right and the left – and their dog is on the threshold of the cave, with its paws outstretched; O listener, were you to look at them closely, you would turn back running away from them, and be filled with their dread. 18 Likewise, We roused them in a miraculous way that they might question one another. One of them asked: "How long did you remain (in this state)?" The others said: "We remained so for a day or part of a day." Then they said: "Your Lord knows better how long we remained in this state. Now send one of you to the city with this coin of yours and let him see who has the best food, and let him buy some provisions from there. Let him be cautious and not inform anyone of our whereabouts. 19 For surely if they prevail against you they would stone you to death or force you back to their religion, and then you will never succeed. 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 They will say there were three, the fourth of them being their dog; and they will say there were five, the sixth of them being their dog - guessing at the unseen; and they will say there were seven, and the eighth of them was their dog. Say, [O Muhammad], "My Lord is most knowing of their number. None knows them except a few. So do not argue about them except with an obvious argument and do not inquire about them among [the speculators] from anyone." 22
