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 And likewise we raised them up that they might question among themselves; there spake a speaker from amongst them: how long have ye tarried? They said we have tarried a day or part of a day. They said, your Lord knoweth best how long ye have tarried; now send one of you with this your money unto the city and let him see which food is purest there, and let him bring you a provision thereof, and let him be circumspect, and let him by no means discover you to anyone. 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 in like manner We disclosed them (to the people of the city) that they might know that the promise of Allah is true, and that, as for the Hour, there is no doubt concerning it. When (the people of the city) disputed of their case among themselves, they said: Build over them a building; their Lord knoweth best concerning them. Those who won their point said: We verily shall build a place of worship over them. 21 (Some) will say: They were three, their dog the fourth, and (some) say: Five, their dog the sixth, guessing at random; and (some) say: Seven, and their dog the eighth. Say (O Muhammad): My Lord is Best Aware of their number. None knoweth them save a few. So contend not concerning them except with an outward contending, and ask not any of them to pronounce concerning them. 22
