Narrated 'Abdullah:
that the Messenger of Allah (ﷺ) said: Whoever takes a false oath to deprive a Muslim of his property, he will meet Allah while He is angry with him. So Al-Ash'ath bin Qais said: By Allah! This was about me. There was a dispute between myself and a Jewish man who denied my right, and I complained against him to the Prophet (ﷺ). So the Messenger of Allah (ﷺ) said to me: 'Do you have any proof?' I said: 'No.' So he said to the Jew: 'Take an oath.' I said: 'O Messenger of Allah! If he takes an oath then I will lose my property.' So Allah, Blessed and Most High, revealed: Verily those who purchase a small gain at the cost of Allah's covenant and their oaths... until the end of the Ayah. (3:77)
