Abu Dawud Book 13, Hadith Number 2941.

Chapter : Not known.

Narated By AbuMas’ud al-Ansari : The Prophet (PBUH) appointed me to collect sadaqah and then said: Go, AbuMas’ud, I should not find you on the Day of Judgment carrying a camel of sadaqah on your back, which rumbles, the one you have taken by unfaithful dealing in sadaqah. He said: If it is so, I will not go. He said: Then I do not force you.
