The Prophet ﷺ said, "Ahead of you lies a pool as wide as the distance between Jarba and Adhruh."In Ibn Muthanna's version it reads, "my pool." He also added that Ubaydullah said, "I asked him about it, and he said they are two towns in Syria, three nights' journey apart." In Ibn Bishr's version it is three days.
