And you might think them awake while they were asleep and We turned them about to the right and to the left, while their dog (lay) outstretching its paws at the entrance; if you looked at them you would certainly turn back from them in flight, and you would certainly be filled with awe because of them. 18 And similarly, We awakened them that they might question one another. Said a speaker from among them, "How long have you remained [here]?" They said, "We have remained a day or part of a day." They said, "Your Lord is most knowing of how long you remained. So send one of you with this silver coin of yours to the city and let him look to which is the best of food and bring you provision from it and let him be cautious. And let no one be aware of you. 19 If they should get knowledge of you they will stone you, or restore you to their creed, then you will not prosper ever. 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, 'Three; and 'their dog was the fourth of them.' They will say, 'Five; and their dog was the sixth of them, guessing at the Unseen. They will say, 'Seven; and their dog was the eighth of them.' Say: 'My Lord knows very well their number, and none knows them, except a few.' So do not dispute with them, except in outward disputation, and ask not any of them for a pronouncement on them. 22
