Narrated Abdullah ibn Abbas: The Holy Prophet ﷺ said to a man whom he asked to take an oath: Swear by Allah except whom there is no god that you have nothing belonging to him, i. e. the plaintiff.

The tradition mentioned above has also been transmitted by Saeed bin ‘Urubah through the chain as narrated by Ibn Minhal. This version has: About an animal and they had no proof. So the Messenger of Allah ﷺ ordered to cast lots about the oath.
