Abu Dawud Book 3, Hadith Number 1645.
Chapter : Not known.
Narated By Malik ibn Nadlah : The Prophet (PBUH) said: Hands are of three types: Allah’s hand is the upper one; the bestower’s hand is the one near it; the beggar’s hand is the lower one. So bestow what is surplus, and do not submit yourself to the demand of your soul.
