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 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 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 We disclosed things to them so that they might know that God's promise was true and there was no doubt about the Hour [Judgement Day]. The people argued about them among themselves. They said, "Build a monument over them. Their Lord knows best concerning them." Those who prevailed in their affair said, "Let us surely build a place of worship over them." 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
