Sahih Bukhari Volume 3, Book 45, Hadith Number 692.

Narated By Abu Wail : Abdullah (bin Mas’ud) said, “Whoever took a false oath in order to grab somebody’s property will meet Allah while Allah will be angry with him.” Allah revealed the following verse to confirm that: “Verily! Those who purchase a small gain at the cost of Allah’s covenant And their oaths… a painful torment.” (3.77)

Al-Ash’ath bin Qais came to us and asked as to what Abu Abdur-Rehman (i.e. Ibn Mas’ud) was telling you.” We related the story to him. On that he said, “He has told the truth. This verse was revealed about me. I had some dispute with another man regarding a well and we took the case before Allah’s Apostle. Allah’s Apostle said (to me), “Produce two witnesses (to support your claim); otherwise the defendant has the right to take an oath (to refute your claim).’ I said, ‘The defendant would not mind to take a false oath.” Allah’s Apostle then said, ‘Whoever took a false oath in order to grab someone else’s property will meet Allah, Allah will be angry with him.’ Allah then revealed what Confirmed it.” Al-Ash’ath then recited the following Verse: “Verily! Those who purchase a small gain at the cost of Allah’s covenant, And their oaths… (to)… they shall have a painful torment!’ (3.77) (See Hadith No. 546)
