Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The Hour will not be established until the earth is filled with oppression and enmity. Then a man from my Ahl al-Bayt (the narrator is in doubt, perhaps the words are: from my progeny) will emerge who will fill the earth with justice and fairness, just as it was previously filled with oppression."
