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 Such (being their state), we raised them up (from sleep), that they might question each other. Said one of them, "How long have ye stayed (here)?" They said, "We have stayed (perhaps) a day, or part of a day." (At length) they (all) said, "Allah (alone) knows best how long ye have stayed here.... Now send ye then one of you with this money of yours to the town: let him find out which is the best food (to be had) and bring some to you, that (ye may) satisfy your hunger therewith: And let him behave with care and courtesy, and let him not inform any one about 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 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 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
