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 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 “Indeed if they come to know about you, they will stone you or turn you back to their religion – and if so, you will never prosper.” 20 And so We made them (the unbelievers) stumble upon them, so that they might know that the promise of Allah is true and that there is no doubt about the Hour. They argued among themselves over their affair, then (the unbelievers) said: 'Build a building over them (their remains). Their Lord knows best who they were. 'But those who prevailed over the matter said; 'We will build around them a Mosque' 21 They will say there were three, the fourth of them being their dog; and they will say there were five, the sixth of them being their dog - guessing at the unseen; and they will say there were seven, and the eighth of them was their dog. Say, [O Muhammad], "My Lord is most knowing of their number. None knows them except a few. So do not argue about them except with an obvious argument and do not inquire about them among [the speculators] from anyone." 22
