"[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."— Yusuf Ali translation
