Musnad Ahmad 561:1

Hassan ibn Musa narrated to us, Hammad ibn Salamah narrated to us, from Dawud ibn Abi Hind, from Abdullah ibn Qays, who said: I heard al-Harith ibn Uqaysh narrating that Abu Barzah said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) saying: "Indeed, among my nation is he who will intercede for more than [the tribes of] Rabi'ah and Mudar. And indeed, among my nation is he who will be magnified for the Fire until he becomes like one of its pillars."
