Musannaf Ibn Abi Shayba 13:2182

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Al-A’mash narrated to us, from Shaqiq, from ‘Abdullah, who said: The Prophet (peace and blessings of Allah be upon him) said: "Whoever swears a false oath (*yamin sabr*) to seize the property of a Muslim man, while he is wicked in it, he will meet Allah while He is angry with him." He said: Then Al-Ash’ath ibn Qays entered and said: "What is Abu ‘Abd al-Rahman narrating to you?" We said: "Such and such." He said: "He spoke the truth. By Allah, it was revealed concerning me. There was a dispute between me and a man from the Jews, so I took the dispute to the Prophet (peace and blessings of Allah be upon him). He said: 'Do you have evidence?' I said: 'No.' He said: 'Then you have his oath.' I said: 'Then he will swear.' The Prophet (peace and blessings of Allah be upon him) said: 'Whoever swears a false oath...' and he mentioned the like of what ‘Abdullah said." Then this verse was revealed: "Indeed, those who exchange the covenant of Allah and their oaths for a small price."
