Sahih Al Bukhari (661)

عن أبي وائل قال: قال عبد الله {من حلف على يمين يستحق بها مالا لقي الله وهو عليه غضبان ثم أنزل الله تصديق ذلك {إن الذين يشترون بعهد الله وأيمانهم} إلى {عذاب أليم} ثم إن الأشعث بن قيس خرج إلينا فقال ما يحدثكم أبو عبد الرحمن فحدثناه بما قال فقال صدق لفي أنزلت كان بيني وبين رجل خصومة في شيء فاختصمنا إلى رسول الله فقال شاهداك أو يمينه فقلت له إنه إذا يحلف ولا يبالي فقال النبي من حلف على يمين يستحق بها مالا وهو فيها فاجر لقي الله  وهو عليه غضبان فأنزل الله تصديق ذلك ثم اقترأ هذه الآية}

Abu Wail narrated: `Abdullah (bin Mas`ud) said: "Whoever takes a (false) oath in order to grab some property (unjustly), Allah will be angry with him when he will meet Him. Allah confirmed that through His Divine Revelation: "Verily! Those who purchase a little gain at the cost of Allah's covenant and their oaths . . . they will have a painful punishment." (3: 77) Al-Ash'ath ibn Qays came to us and asked, 'What is Abu Abdur-Rahman (i.e. `Abdullah) telling you? 'We told him what he was narrating to us. He said, 'He was telling the truth; this Divine Verse was revealed in connection with me. There was a dispute between me and another man about something and the case was filed before Allah's Messenger (peace be upon him) who said, 'Produce your two witnesses or else the defendant is to take an oath.' I said, the defendant will surely take a (false) oath caring for nothing.' The Prophet (peace be upon him) said, 'Whoever takes a false oath in order to grab (other's) property, then Allah will be angry with him when he will meet Him.' Then Allah revealed its confirmation. Al-Ash‘ath then recited the above Divine Verse." (3: 77)
