It is narrated from Sayyiduna Abu Hurayrah and Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) will be the custodian and companion of my Pond (Hawd) on the Day of Resurrection. In it there will be cups as numerous as the stars, and the breadth of my Pond is equal to the distance from al-Jabiyah to San'a."
Only his son Sa'id narrated this hadith from Musa bin Wardan, and only Ibn Lahi'ah from Sa'id, while Rawh bin Salah is alone in narrating it.
