Musnad Ahmad 26:548

Yahya narrated to us, from Sufyan, 'Asim narrated to me, from Zirr, from 'Abdullah, from the Prophet (peace and blessings of Allah be upon him), who said: "The world will not pass away — or the world will not come to an end — until a man from the people of my house rules over the Arabs, whose name matches my name."
