The Prophet ﷺ said, "Whoever seizes the right of a Muslim man through a false oath, Allah has made the Fire obligatory for him and has forbidden Paradise to him."A man asked him, "Even if it is something trifling, Messenger of Allah?"He replied, "Even if it is a twig from an arak tree."
حدثنا سليمان بن داود الهاشمي حدثنا إسماعيل يعني ابن جعفر أخبرني العلاء عن معبد بن كعب السلمي عن أخيه عبد الله بن كعب
أن النبي ﷺ قال من اقتطع حق امرئ مسلم بيمينه فقد أوجب الله له بها النار وحرم عليه الجنة فقال له رجل وإن كان شيئا يسيرا يا رسول الله قال وإن قضيبا من أراك
Its isnad is sahih. Ala is Ibn Abdul-Rahman, and Mabad bin Kaab Sulami is a reliable narrator whose hadith is found in Sahihayn. His brother Abdullah is a trustworthy narrator among the senior successors, and it is said that he had a sighting of the Prophet. The hadith has already appeared in similar form at 21745.
