It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The Hour will not be established until a man from my household becomes ruler whose name matches my name; he will fill the earth with justice and equity just as it will have been filled with oppression and tyranny."
