Sayyiduna Qurrah bin Iyas (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "The earth will be filled with oppression and tyranny just as it had been filled with justice and fairness, until Allah sends a man from my progeny whose name is my name and whose father's name is my father's name. He will fill it with justice and fairness just as it had been filled with oppression and tyranny. He will remain among you for seven or eight years, and if more, then nine years. During that time the sky will not withhold anything of its rain, nor will the earth withhold anything of its produce."
