Abdullah bin Masud reported,

The Messenger of Allah ﷺ said, "Whoever swears a binding oath in order to seize the property of a Muslim by it, while he is lying in that oath, will meet Allah with Allah angry at him."The narrator continued, Ashath bin Qays then came in and asked, "What is Abu Abdul-Rahman telling you?"They said, "Such and such."He said, "Abu Abdul-Rahman has spoken the truth. It was concerning me that this was revealed. There was a dispute between me and another man over a piece of land in Yemen, and I brought the case against him before the Prophet ﷺ.He asked me, "Do you have any proof?"I said, "No."He said, "Then he must take an oath."I said, "In that case he will simply swear."At that point the Messenger of Allah ﷺ said, "Whoever swears a binding oath in order to seize the property of a Muslim by it, while he is lying in that oath, will meet Allah with Allah angry at him."Then this was revealed, "Indeed, those who exchange the covenant of Allah and their oaths for a small price" [Al Imran 3:77], to the end of the verse.

عن عبد الله بن مسعود

عن رسول الله ﷺ قال: من حلف على يمين صبر يقتطع بها مال امرئ مسلم هو فيها فاجر، لقي الله وهو عليه غضبان. قال: فدخل الأشعث بن قيس، فقال: ما يحدثكم أبو عبد الرحمن؟ قالوا كذا وكذا. قال: صدق أبو عبد الرحمن، في نزلت، كان بيني وبين رجل أرض باليمن، فخاصمته إلى النبي ﷺ، فقال: هل لك بينة. فقلت: لا. قال: فيمينه. قلت: إذن يحلف. فقال رسول الله ﷺ عند ذلك: من حلف على يمين صبر يقتطع بها مال امرئ مسلم وهو فيها فاجر لقي الله وهو عليه غضبان. فنزلت {إن الذين يشترون بعهد الله وأيمنهم ثمنا قليلا} [آل عمران: ٧٧] إلى الآخر الآية.
