Mukhtasar Muslim

Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "There will be a reservoir before you, the distance between its two banks will be like that between Jarba’ and Adhrah." In another narration, it is stated: "My reservoir will be before you." And in another narration, Ubaydullah says: "I asked him (i.e., Nafi‘) what are Jarba’ and Adhrah?" He replied: "They are two villages in Syria, and the distance between them is that of three nights’ journey." In another narration, it is stated: "It is a distance of three days’ journey."
