The Prophet (ﷺ) said: " Whoever takes a false oath to deprive somebody of his property will meet Allâh while He will be angry with him." Allâh revealed: " Verily those who purchase a small gain at the cost of Allâh's Covenant, and their oaths." (V.3:77) Al-Ash'ath came (to the place where 'Abdullah was narrating) and said, "What has ' Abdur (i.e. 'Abdullâh) been telling you? This Verse was revealed concerning me. I had a well in the land of a cousin of mine. The Prophet (ﷺ) asked me to bring witnesses (to confirm my claim). I said, 'I don't have witnesses. ' He said, 'Let the defendant take an oath then. ' I said, 'O Allâh's Messenger (ﷺ)! He will take a (false) oath immediately ! ' Then the Prophet (ﷺ) mentioned as above and Allâh revealed the Verse to confirm what he said." [3:546-O.B]
