'Abdullah b. Abu Aufa said that it was the common practice of the Mes- senger of Allaah (sallAllaahu alayhi wa sallam) that when the people brought to him sadaqa he blessed them: 0 Allaah, bless them. So when Abu Aufa brought to him Sadaqa he (the Prophet) said: 0 Allaah, bless, the posterity of Abu Aufa.
