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 surely if they prevail against you they would stone you to death or force you back to their religion, and then you will never succeed. 20 Thus We disclosed things to them so that they might know that God's promise was true and there was no doubt about the Hour [Judgement Day]. The people argued about them among themselves. They said, "Build a monument over them. Their Lord knows best concerning them." Those who prevailed in their affair said, "Let us surely build a place of worship over them." 21 (Some) say they were three, the dog being the fourth among them; (others) say they were five, the dog being the sixth,- doubtfully guessing at the unknown; (yet others) say they were seven, the dog being the eighth. Say thou: "My Lord knoweth best their number; It is but few that know their (real case)." Enter not, therefore, into controversies concerning them, except on a matter that is clear, nor consult any of them about (the affair of) the Sleepers. 22
