Musnad Ahmad 3553

It was narrated from ‘Abdullah (رضي الله عنه) that The Prophet (ﷺ) said: "Whoever swears an oath to take the property of a Muslim unlawfully will meet Allah when He is angry with him.” And The Messenger of Allah (ﷺ) recited the confirmation of that from the Book of Allah, may He be glorified and exalted: “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.” (Al 'Imran 3:77).
