And you would think them awake, while they were asleep. And We turned them to the right and to the left, while their dog stretched his forelegs at the entrance. If you had looked at them, you would have turned from them in flight and been filled by them with terror. 18 And thus did We rouse them that they might question each other. A speaker among them said: How long have you tarried? They said: We have tarried for a day or a part of a day. (Others) said: Your Lord knows best how long you have tarried. Now send one of you with this silver (coin) of yours to the city, then let him see which of them has purest food, so let him bring you provision from it, and let him behave with gentleness, and by no means make your case known to any one: 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 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) 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
