Sahih Bukhari, Chapter: Mortgaging In Places Occupied By Settled Population

Abdullah (bin Masud) 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-Ashath bin Qais came to us and asked as to what Abu Abdur-Rahman (i.e. Ibn Masud) 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 (SAW). Allah's Apostle (SAW) 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 (SAW) 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-Ashath 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. 552)
