Sahih al-Bukhari 6516

Abu Wa'il related from 'Abdullah [ibn Mas'ud] that the Prophet, may Allah bless him and grant him peace, said, "said, "Whoever swears an oath in which he lies in order to take the property of a Muslim by it, will meet Allah with anger covering him." Allah revealed, 'Those who sell Allah's contract and their own oaths for a paltry price...' (3:77) Then al-Ash'ath came while 'Abdullah was relating (that) to us. He said, 'It was revealed about me and a man wih whom I had a dispute concerning a well. The Prophet, may Allah bless him and grant him peace, said, 'Do you have a clear proof?' No,' I answered. He said, 'Then he will take an oath.' I said, 'Then he will swear a [false] oath!' Then it was revealed, 'Those that sell the faith that they owe Allah.'" XXXI. Judgement regarding property, whether large or small Ibn 'Uyayna related from Ibn Shubruma [Qadi of Kufa], "Judgement in the same in both a little property or a lot of property."
