According to Hudhaifa, the Messenger of Allah (saas) said:
... In his time all water will become sweet, rivers will grow longer, the earth will increase its yields, and give its treasures out. (Al-Uqayli, An-Najmu's-saqib fi Bayan Anna'l Mahdi min Awladi Ali b. Abu Talib Ale't-Tamam ve'l Qamal, p. 43)
... Hazrat Mahdi (as) will extract treasures...(Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 33)
IN HIS [HAZRAT MAHDI’S (AS)] TIME UNDERGROUND TREASURES, RICHES AND OTHER MINES WILL BE BROUGHT FORTH.(Al-Mahdi Al-Maw’ud, Vol. 1, pp. 264, 275, 277, 285, 287, 288, 311, 318, Vol. 2, p. 11)
IN HIS TIME THE EARTH WILL CAST FORTH THE TREASURES WITHIN IT.(Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 43)
... THE EARTH WILL CAST FORTH ALL THE WEALTH IT HAS CONCEALED WITHIN IT IN THE FORM OF GOLD AND SILVER PILLARS.(Al-Sharani, Mukhtasar Tazkirah al-Qurtubi, p. 464)
Hazrat Imam Bakr (as) states: “When our Qaim [Hazrat Mahdi (as)] appears, ALL THE EARTH’S MINERALS AND TREASURES WILL PASS INTO HIS HANDS.” (Bihar Al-Anwar, Vol. 52, p. 351)
