And thou wouldst have deemed them awakes whereas they were asleep and We turned them over on the right side and on the left side, while their dog stretched forth his two forelegs on the threshold. If thou hadst observed them, thou wouldst have surely turned away from them in fright, and wouldst have surely been filled with awe 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 if they come to know of you, they will stone you (to death or abuse and harm you) or turn you back to their religion, and in that case you will never be successful." 20 And so We made them (the unbelievers) stumble upon them, so that they might know that the promise of Allah is true and that there is no doubt about the Hour. They argued among themselves over their affair, then (the unbelievers) said: 'Build a building over them (their remains). Their Lord knows best who they were. 'But those who prevailed over the matter said; 'We will build around them a Mosque' 21 (With regard to the number of the youths) some say, "There were three and the dog was the fourth one," Others say, "There were five and the dog was the sixth one." In reality, they are just feeling around in the dark. Still some of them say, "There were seven and the dog was the eighth one." (Muhammad), say, "My Lord has the best knowledge of their number. You know very little about it." Do not insist on arguing with them, but merely tell them the story as it has been revealed to you and do not ask anyone about them. 22
