What common practice was the Messenger of Allah (saw) known to do when people brought sadaqa to him?
 'Abdullah b. Abu Aufa said that it was the common practice of the Mes- senger of Allah (may peace be upon him) that when the people brought to him sadaqa he blessed them:                      0 Allah, bless them. So when Abu Aufa brought to him Sadaqa he (the Holy Prophet) said: 0 Allah, bless, the posterity of Abu Aufa.
