‘Uday ibn ‘Umayrah (may Allah be pleased with him) reported that the Messenger (may Allah's peace and blessings be upon him) said: "If any of you is assigned by us to a position but conceals a needle or more from us, it will amount to misappropriation and he will be called upon to restore it on the Day of Judgment." A black man from the Ansār stood up - I can still see him - and said: "O Messenger of Allah, take back your assignment from me." The Prophet (may Allah's peace and blessings be upon him) said: "What has happened to you?" The man replied: "I heard you say such-and-such." The Prophet replied: "I say that even now: Whosoever from you is appointed by us to a position, he should render an account of everything, big or small, and whatever he is given therefrom, he should take, and he should desist from taking what is unlawful."
