Musnad Ahmad 769:14

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from 'Amr ibn Murrah, who said: I heard 'Abdullah ibn Abi Awfa—and he was one of the Companions of the Tree—say: When the Messenger of Allah (peace and blessings of Allah be upon him) was brought charity, he would say: "O Allah, send blessings upon them." And my father brought him his charity, so he said: "O Allah, send blessings upon the family of Abi Awfa."
