Musnad Ahmad 8:15

Ishaq ibn Isa narrated to us, Malik—meaning Ibn Anas—narrated to me, from Salim Abu al-Nadr, from Amir ibn Sa’d ibn Abi Waqqas, who said: I heard my father say: I never heard the Messenger of Allah, peace and blessings of Allah be upon him, say to any living person walking upon the earth: "He is among the people of Paradise," except for Abdullah ibn Salam.
