Musnad Ahmad Hadith 3574

The Messenger of Allah (ﷺ) said: "Whoever swears an oath in which he is lying in order to usurp the property of a Muslim will meet Allah when He is angry with him." Al-Ash'ath bin Qais said: By Allah, that was said concerning me. There was a dispute between me and a Jewish man concerning some land; he denied my right, so I took him to the Prophet (ﷺ). The Messenger of Allah (ﷺ) said to me. “Do you have any proof?" I said: No. He said to the Jewish man: "Swear an oath." I said: O Messenger of Allah, then he will swear an oath and take my property. Then Allah, may He be glorified and exalted, revealed the verse: “Verily, those who purchase a small gain at the cost of Allah's Covenant and their oaths, they shall have no portion in the Hereafter (Paradise). Neither will Allah speak to them nor look at them on the Day of Resurrection nor will He purify them, and they shall have a painful torment" (Al ‘Imran 3:77)]
