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 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 "For if they should come upon you, they would stone you or force you to return to their cult, and in that case ye would never attain prosperity." 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 Some will say: 'They were three; their dog was the fourth' Others, guessing at the Unseen, will say: 'They were five and their dog was the sixth' And yet others: 'Seven; their dog was the eighth' Say: 'My Lord knows best their number. Except for a few none know their number' Therefore, do not dispute with them except in outward disputation, and do not ask any of them concerning them. 22
