It is narrated on the authority of Abu Umama that the Messenger of Allah (ﷺ) observed: He who appropriated the right of a Muslim by (swearing a false) oath, Allah would make Hell-fire necessary for him and would declare Paradise forbidden for him. A person said to him: Messenger of Allah, even if it is something insignificant? He (the Holy Prophet) replied: (Yes) even if it is the twig of the arak tree.
