And you would have thought them awake, while they were asleep. And We turned them on their right and on their left sides, and their dog stretching forth his two forelegs at the entrance [of the Cave or in the space near to the entrance of the Cave (as a guard at the gate)]. Had you looked at them, you would certainly have turned back from them in flight, and would certainly have 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 If they should get knowledge of you they will stone you, or restore you to their creed, then you will not prosper ever. 20 AND IN THIS way have We drawn [people's] attention to their story, so that they might know - whenever they debate among themselves as to what happened to those [Men of the Cave] that God's promise [of resurrection] is true, and that there can be no doubt as to [the coming of] the Last Hour. And so, some [people] said: "Erect a building in their memory; God knows best what happened to them." Said they whose opinion prevailed in the end: "Indeed, we must surely raise a house of worship in their memory!" 21 (Some) say: (They are) three, the fourth of them being their dog; and (others) say: Five, the sixth of them being their dog, making conjectures at what is unknown; and (others yet) say: Seven, and the eighth of them is their dog. Say: My Lord best knows their number, none knows them but a few; therefore contend not in the matter of them but with an outward contention, and do not question concerning them any of them. 22
