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 so, [in the course of time,] We awakened them; and they began to ask one another [as to what had happened to them]. One of them asked: "How long have you remained thus?" [The others] answered: "We have remained thus a day, or part of a day." Said they [who were endowed with deeper insight]: "Your Sustainer knows best how long you have thus remained. Let, then, one of you go with these silver coins to the town, and let him find out what food is purest there, and bring you thereof [some] provisions. But let him behave with great care and by no means make anyone aware of you: 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 similarly, We caused them to be found that they [who found them] would know that the promise of Allah is truth and that of the Hour there is no doubt. [That was] when they disputed among themselves about their affair and [then] said, "Construct over them a structure. Their Lord is most knowing about them." Said those who prevailed in the matter, "We will surely take [for ourselves] over them a masjid." 21 Some will say concerning them: "They were three and their dog, the fourth"; and some will say: "They were five, and their dog, the sixth" -- all this being merely guesswork; and still others will say: "They were seven, and their dog, the eighth." Say: "My Lord knows their number best. Only a few know their correct number. So do not dispute concerning their number, but stick to what is evident, and do not question anyone about them." 22
