Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever swears a false oath in order to seize the wealth of a Muslim man in any matter, will meet Allah while Allah is angry with him. Then this verse was revealed: "Indeed, those who exchange the covenant of Allah and their oaths for a small price..." (Aal-e-Imran: 77) (Those who obtain a small price in exchange for Allah's covenant and their false oaths.) Ash'ath bin Qais (may Allah be pleased with him) came and asked: Abu Abdur Rahman (the kunyah of Abdullah bin Mas'ud, may Allah be pleased with him), what are you narrating? We said: We are narrating this hadith. He said: He is telling the truth, this verse was revealed about me. There was a dispute over land between me and a man from my tribe. I brought that dispute to the Prophet (peace and blessings be upon him), so he said: Bring your evidence. I had no evidence, so he said to the other man: Swear an oath. I said: O Messenger of Allah! He will surely swear an oath. The Messenger of Allah (peace and blessings be upon him) said: Whoever swears a false oath in order to seize the wealth of a Muslim man in any matter, will meet Allah while Allah is angry with him. Then this verse was revealed: "Indeed, those who exchange the covenant of Allah and their oaths for a small price..." (Aal-e-Imran: 77)
