Sayyiduna Abdullah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Whoever swears a binding oath in order to usurp the property of a Muslim brother, while he is lying in that oath, will meet Allah Almighty in a state where Allah Almighty is angry with him."
