Sahih Bukhari | Volume 8 | Hadith Number 653
Narrated by '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."
