Thou wouldst have thought them awake, as they lay sleeping, while We turned them now to the right, now to the left,' and their dog 'stretching its paws on the threshold. Hadst thou observed them surely thou wouldst have turned thy back on them in flight, and been filled with terror of them. 18 And similarly We awakened them so that they may enquire about each other; a speaker among them said, “How long have you stayed here?” Some among them said, “We have stayed a day or part of a day”; the others said, “Your Lord well knows how long you have stayed; therefore send one of you to the city with this silver coin – he may then check which food available there is purer, in order to bring some of it for you to eat – and he must be courteous and not inform anyone about you.” 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 did We make their case known to the people, that they might know that the promise of Allah is true, and that there can be no doubt about the Hour of Judgment. Behold, they dispute among themselves as to their affair. (Some) said, "Construct a building over them": Their Lord knows best about them: those who prevailed over 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, guessing at the unseen; (yet others) say they were seven, the dog being the eighth. Say (O Muhammad SAW): "My Lord knows best their number; none knows them but a few." So debate not (about their number, etc.) except with the clear proof (which We have revealed to you). And consult not any of them (people of the Scripture, Jews and Christians) about (the affair of) the people of the Cave. 22
