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 Likewise, We awakened them (from their long deep sleep) that they might question one another. A speaker from among them said: "How long have you stayed (here)?" They said: "We have stayed (perhaps) a day or part of a day." They said: "Your Lord (Alone) knows best how long you have stayed (here). So send one of you with this silver coin of yours to the town, and let him find out which is the good lawful food, and bring some of that to you. And let him be careful and let no man know of you. 19 For if they should come upon us, they will stone us to death or force us to revert to their faith whereafter we shall 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: "They were three, and their dog was the fourth;" and some will also say: "They were five and their dog was the sixth," -- guessing in the dark. And some will even say: "They were seven, and their dog the eighth." Say: "My Lord alone knows best their number; none but only a few know of them." So do not argue about it with them but lightly, and do not enquire about them from any one of them. 22
