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 And likewise we raised them up that they might question among themselves; there spake a speaker from amongst them: how long have ye tarried? They said we have tarried a day or part of a day. They said, your Lord knoweth best how long ye have tarried; now send one of you with this your money unto the city and let him see which food is purest there, and let him bring you a provision thereof, and let him be circumspect, and let him by no means discover you to anyone. 19 Verily they, if they come to know of you, would stone you or make you revert to their faith, and lo! then ye will never fare well. 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 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
