Ibn ‘Abbas wrote to me that the Messenger of Allah (ﷺ)had defendant should take an oath.
Sunan Abi Dawud Book 25, Hadith 49
← Previous Hadith About an animal and they had no proof. So the Messenger of Allah (ﷺ) ordered to cast lots about the oath.

Sunan Abi Dawud Book 25, Hadith 48 Next Hadith → 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.

Sunan Abi Dawud Book 25, Hadith 50
