Abu Dawud Book 18, Hadith Number 3574.

Chapter : Not known.

Narated By Adi ibn Umayrah al-Kindi : The Prophet (PBUH) said: O people, if any of you is put in an administrative post on our behalf and conceals from us a needle or more, he is acting unfaithfully, and will bring it on the Day of Resurrection. A black man from the Ansar, as if I am seeing him, stood and said: Apostle of Allah, take back from me my post. He asked: What is that? He replied: I heard you say such and such. He said: And I say that. If we appoint anyone to an office, he must bring what is connected with it, both little and much. What he is given, he may take, and he must refrain from what is kept away from him.
