Mishkat al-Masabih #1691

‘Abdallah b. Abu Aufa told that the Prophet said when people brought him their sadaqa, “O God, bless the family of so and so.” He told how, when his father brought him his sadaqa, he said, “O God, bless the family of Abu Aufa.” (Bukhari and Muslim.) A version says that when a man brought the Prophet his sadaqa he said, “O God, bless him.”
