Musnad Ahmad 536:8

Muhammad ibn Ja'far narrated to us, he said: Shu'bah narrated to us, from Isma'il, he said: I heard Qays narrating from 'Adi ibn 'Amirah, from the Prophet, may Allah bless him and grant him peace, that he said: "Whoever we appoint from among you to a task, and he conceals from us even a needle, it is a misappropriation (ghulul) which he will bring on the Day of Resurrection." A man from the people, dark-skinned and tall, from the Ansar, stood up and said: "I have no need for your task." The Messenger of Allah, may Allah bless him and grant him peace, said to him: "Why?" He said: "I heard you just now saying [that]." He said: "And I say it now: Whoever we appoint from among you to a task, let him bring its little and its much. Whatever he is given of it, he shall take, and whatever he is forbidden from, he shall refrain."
