Musnad Ahmad 769:10

Waki’ narrated to us, from Shu’bah, from ‘Amr ibn Murrah, who said: I heard Ibn Abi Awfa say: When a man would bring the charity of his wealth to the Prophet, may Allah bless him and grant him peace, he would pray for him. So I brought him the charity of my father’s wealth, and he said: "O Allah, bless the family of Abi Awfa."
