Musnad Ahmad 192:2

'Affan narrated to us, Wuhayb narrated to us, he said: Khalid narrated to us, from 'Abdullah ibn Shaqiq, from 'Abdullah ibn Abi al-Jad'a', that he heard the Prophet, peace and blessings of Allah be upon him, saying: "There shall certainly enter Paradise, through the intercession of a man from my Ummah, more than [the number of] Banu Tamim." They said: "O Messenger of Allah, [more than] you?" He said: "More than me, more than me." I said: "Did you hear it from the Messenger of Allah?" He said: "I heard it."
