And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe 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 they would certainly stone us to death or force us to follow their religion. Then we shall never be able to have everlasting happiness." 20 AND IN THIS way have We drawn [people's] attention to their story, so that they might know - whenever they debate among themselves as to what happened to those [Men of the Cave] that God's promise [of resurrection] is true, and that there can be no doubt as to [the coming of] the Last Hour. And so, some [people] said: "Erect a building in their memory; God knows best what happened to them." Said they whose opinion prevailed in the end: "Indeed, we must surely raise a house of worship in their memory!" 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
