Whenever a group brought their charity to the Prophet ﷺ, he would say, "O Allah, send blessings upon the family of so-and-so." When my father brought his charity, the Prophet ﷺ said, "O Allah, send blessings upon the family of Abu Awfa."
كان النبي ﷺ إذا أتاه قوم بصدقتهم، قال: اللهم صل على آل فلان فأتاه أبي بصدقته فقال: اللهم صل على آل أبي أوفى.
Bukhari narrated it in the Book of Zakat (1497), and Muslim narrated it in the Book of Zakat (1078), both through the route of Shubah, from Amr (that is, Ibn Murrah), from Abdullah bin Abu Awfa, who related the hadith.
