(M’izaab) If one sees the Gutter of Mercy in a dream, which is located on the roof of the Holy Ka’aba in Mecca inside a mosque or a house in a dream, it carries the same interpretation as that of seeing the Well of Zamzam in a dream. Standing under the Gutter of Mercy at the Holy Ka’aba in a dream means that one’s wishes will come true, and particularly if pure fresh water pours through it. However, if murky water comes through it, then it means the opposite. (Also see Gutter | Ka’aba | Zamzam)
