Narrated 'Abdullah: that the Messenger of Allah ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ). So the Messenger of Allah ( صلی اللہ علیہ وسلم ) 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)"

‘Abdullah bin Mas’ud (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said:“Whoever swears a false oath in order to unlawfully seize the wealth of a Muslim, will meet Allah while He is angry with him.”Ash’ath bin Qais (may Allah be pleased with him) says: By Allah! The Prophet narrated this hadith concerning me. There was a piece of land shared between me and a Jew. He denied my share, so I brought him to the Prophet (peace and blessings of Allah be upon him). The Messenger of Allah asked me:“Do you have any witnesses?”I replied: No. So he said to the Jew:“Take an oath.”I said: O Messenger of Allah! He will swear an oath and consume my property. Then Allah revealed this verse «إن الذين يشترون بعهد الله وأيمانهم ثمنا قليلا» “Indeed, those who exchange the covenant of Allah and their oaths for a small price...”(Aal ‘Imran: 77).

Imam Tirmidhi says:
1- The hadith of Ibn Mas’ud is Hasan Sahih (good and authentic).
2- In this chapter, hadiths have also been narrated from Wa’il bin Hujr, Abu Musa, Abu Umamah bin Thalabah Al-Ansari, and Imran bin Husain (may Allah be pleased with them).
