The Messenger of Allah ﷺ said, "Whoever seizes the right of a Muslim man through a false oath, Allah has made the Fire obligatory for him and forbidden Paradise to him."A man asked him, "Even if it is something trivial, Messenger of Allah?"He replied, "Even if it is a twig from an arak tree."
أن رسول الله ﷺ قال: من اقتطع حق امرئ مسلم بيمينه فقد أوجب الله له النار، وحرم عليه الجنة. فقال له رجل: وإن كان شيئا يسيرا يا رسول الله قال: وإن قضيبا من أراك.
Muslim narrated it in the chapter on Iman (137) through several routes from Ismail bin Jafar, who said, Ala (that is, Ibn Abdul-Rahman, the freedman of Hurqa) informed us, from Mabad bin Kaab Sulami, from his brother Abdullah bin Kaab, from Abu Umama, and he mentioned the same.
