English translation
3581. 'Adiyy bin 'Umairah Al-Kindī narrated that the Messenger of Allāh ﷺ said: "O people, whoever among you is appointed by us to do some work, and he conceals (for himself) a needle or less from us, it will be a yoke of iron on his neck that he will bring on the Day of Resurrection." An Anṣārī man who was black – it is as if I can see him now – stood up and said: "O Messenger of Allāh, dismiss me from working for you." He said: "Why is that?" He said: "I heard you say such and such." He said: "I do say that. Whoever we appoint to do some work, let him bring everything, whether it is a little or a lot. Whatever he is given, he may take, and whatever he is forbidden, let him refrain from it." (Sahih)
