Musnad Abu Ya'la al-Mawsili 42:155

Qatan ibn Nusayr narrated to us, 'Adi ibn Abi 'Amarah narrated to us, Matar al-Warraq narrated to us, from Abu al-Siddiq, from Abu Sa'id, from the Messenger of Allah (may Allah bless him and grant him peace), who said: "There shall certainly arise over my Ummah, from the people of my household, a man with a hooked nose and a receding hairline. He will fill the earth with justice just as it was filled with oppression and tyranny. He will rule for seven years."
