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 As such We revived them so that they might question one another. 'How long have you stayed here' asked one of them. 'We have been here a day, or part of it' they replied. They said: 'Your Lord knows best how long we have stayed here. Let one of you go to the city with this silver (coin) and let him search for one who has the purest food and bring provision from it. Let him be courteous, but let no one sense it is you. 19 for, behold, if they should come to know of you, they might stone you to death or force you back to their faith - in which case you would never attain to any good!" 20 Thus did We make their case known to the people of the city so that they might know that Allah's promise is true, and that there is absolutely no doubt that the Hour will come to pass. But instead of giving thought to this, they disputed with one another concerning the People of the Cave, some saying: "Build a wall over them. Their Lord alone knows best about them." But those who prevailed over their affairs said: "We shall build a place of worship over them." 21 (Some) say they were three, the dog being the fourth among them; (others) say they were five, the dog being the sixth,- doubtfully guessing at the unknown; (yet others) say they were seven, the dog being the eighth. Say thou: "My Lord knoweth best their number; It is but few that know their (real case)." Enter not, therefore, into controversies concerning them, except on a matter that is clear, nor consult any of them about (the affair of) the Sleepers. 22
