Oaths and Vows

Bukhari :: Book 8 :: Volume 78 :: Hadith 653

Narrated 'Abdullah:

The Prophet said, "Whoever swears falsely in order to grab the property of a Muslim (or of his brother), Allah will be angry with him when he meets Him." Allah then revealed in confirmation of the above statement:--'Verily those who purchase a small gain at the cost of Allah's Covenant and their own oaths.' (3.77) Al-Ash'ath said, "This Verse was revealed regarding me and a companion of mine when we had a dispute about a well."
