Sahih al-Bukhari 6659, 6660

Muhammad ibn Bashshar narrated to me; Ibn Abi Adi narrated to us, from Shu'bah, from Sulayman and Mansur, from Abu Wa'il, from Abdullah, may Allah be pleased with him, from the Prophet, peace and blessings be upon him, who said: ‘Whoever swears a false oath to seize the property of a Muslim man—or he said, his brother—will meet Allah while He is angry with him.’ Allah revealed in confirmation the verse beginning: Indeed, those who sell Allah's covenant. Sulayman added in his report: Al-Ash'ath ibn Qays passed by and asked what Abdullah was relating. They told him, and al-Ash'ath said it was revealed concerning him and a companion of his, about a well they shared.
