Sahih Al Bukhari (659)

عن عبدالله (رضي الله عنه) قال "قال رسول الله (صلى الله عليه وسلم) من حلف على يمين وهو فيها فاجر ليقتطع بها مال امرئ مسلم لقي الله وهو عليه غضبان" قال فقال الأشعث بن قيس في والله كان ذلك كان بيني وبين رجل من اليهود أرض فجحدني فقدمته إلى النبي (صلى الله عليه وسلم) فقال لي رسول الله (صلى الله عليه وسلم) ألك بينة قال قلت لا قال فقال لليهودي احلف قال قلت يا رسول الله إذا يحلف ويذهب بمالي قال فأنزل الله تعالى { إن الذين يشترون بعهد الله وأيمانهم ثمنا } إلى آخر الآية.

`Abdullah narrated: Allah's Messenger (peace be upon him) said: "If somebody takes a false oath in order to get the property of a Muslim (unjustly) by that oath, then Allah will be angry with him when he will meet Him." Al-Ash'ath informed me: "By Allah! This was said regarding me. There was a dispute about a piece of land between me and a man from the Jews who denied my right. I took him to the Prophet (peace be upon him). Allah's Messenger (peace be upon him) asked me, 'Do you have an evidence?' I replied in the negative. He said to the Jew, 'Take an oath.' I said, 'O Allah's Messenger! He will surely take an oath and take my property unjustly." So, Allah revealed:- "Verily! Those who purchase a little gain at the cost of Allah's covenant and their oaths…." (3.77)
