(64) باب صَلاَةِ الإِمَامِ وَدُعَائِهِ لِصَاحِبِ الصَّدَقَةِ
Narrated 'Abdullah bin Abu Aufa :
Whenever a person came to the Prophet (ﷺ) with his alms, the Prophet (ﷺ) wouldsay, "O Allah! Send your Blessings upon so and so." My father went to the Prophet (ﷺ) with his alms and the Prophet (ﷺ) said, "O Allah! Send your blessings upon the offspring of Abu Aufa."
