Then there will arise a man of Quraysh whose maternal uncles belong to Kalb and send against them an expeditionary force which will be overcome by them, and that is the expedition of Kalb. Disappointed will be the one who does not receive the booty of Kalb. He will divide the property, and will govern the people by the Sunnah of their Prophet (ﷺ) and establish Islam on Earth. He will remain seven years, then die, and the Muslims will pray over him.
Abu Dawud said: Some transmitted from Hisham "nine years" and some "seven years".
