Thou wouldst have thought them awake, as they lay sleeping, while We turned them now to the right, now to the left,' and their dog 'stretching its paws on the threshold. Hadst thou observed them surely thou wouldst have turned thy back on them in flight, and been filled with terror of them. 18 Even so We roused them that they may question one another. One of them asked: "How long have you stayed here?" They said: "A day or less than a day." "Your Lord knows best," they said, "how long you have stayed. So send one of you to the town with this money of yours to look for wholesome food and bring it for you; but he should be careful not to let your presence known. 19 For they, if they should come to know of you, will stone you or turn you back to their religion; then ye will never prosper. 20 And this is how We made them known for people to know that the promise of Allah is true and that there is no doubt concerning the Last Day; when the people began disputing among themselves regarding them, they said, “Construct a building over their cave”; their Lord well knows them; those who dominated in this matter said, “We promise we will build a mosque over them.” 21 So the people will now say, “They are three, their dog is the fourth”; and some will say, “They are five, their dog is the sixth” – just blind guesses; and some will say, “They are seven, and their dog is the eighth”; proclaim (O dear Prophet Mohammed – peace and blessings be upon him), “My Lord well knows their number – no one knows them except a few”; therefore do not debate concerning them except what has occurred, and do not ask any of the People of the Book(s) anything concerning them. 22
