Sahih Muslim 1833a

Abu Bakr ibn Abi Shaybah narrated to us; Waki ibn al-Jarrah narrated to us; Ismail ibn Abi Khalid narrated to us, from Qays ibn Abi Hazim, from Adi ibn Umayrah al-Kindi, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: “Whoever among you is appointed by us to a position and conceals from us even a needle or anything greater than that has committed misappropriation, and he will bring it on the Day of Resurrection.” A dark-complexioned man from the Ansar stood up—I can almost see him now—and said, “Messenger of Allah, take back your appointment from me.” He asked, “What is the matter with you?” The man said, “I heard you say such-and-such.” He replied, “I say it now as well: Whoever among you is appointed by us to a position must bring everything, little or much. Whatever he is given from it, he may take; whatever he is forbidden, he must refrain from.”
