Alqamah ibn Wail reported from his father that a man from Hadramawt and a man from Kinda came to the Prophet (SAW) The Hadrami pleaded, “O Messenger of Allah, this man has seized my land.” The Kindi said, “It is my land and in my hands; he has no right over it.” The Prophet (SAW) said to the Hadrami, “Do you have a witness?” He said, “No.” The Prophet (SAW) said, “Then you can ask him to state on an oath.” He said, “0 Messenger of Allah, this man is a profligate, an immoral. He will not mind swearing at anything. He is not righteous.” The Prophet said, “You haveno way but to get him to swear.” So, the man turned to take an oath. When he turned, Allah’s Messenger i’ said, “If he swears over his property to sieze it unjustly then when he meets Allah (on the Day of Resurrection), He will turn away from him.”
[Muslim 139, Abu Dawud 3245]
