You might have thought them awake, though they were sleeping. We turned them about to the right and to the left, while their dog stretched its paws at the entrance. Had you seen them you would surely have become filled with terror and turned your back on them in flight. 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 "For if they should come upon you, they would stone you or force you to return to their cult, and in that case ye would never attain prosperity." 20 And thus We made 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. (Remember) when they (the people of the city) disputed among themselves about their case, they said: "Construct a building over them, their Lord knows best about them," (then) those who won their point said (most probably the disbelievers): "We verily shall build a place of worship over them." 21 Some will say: 'They were three; their dog was the fourth' Others, guessing at the Unseen, will say: 'They were five and their dog was the sixth' And yet others: 'Seven; their dog was the eighth' Say: 'My Lord knows best their number. Except for a few none know their number' Therefore, do not dispute with them except in outward disputation, and do not ask any of them concerning them. 22
