Allah's Messenger (ﷺ) said, "There is no Diya for persons killed by animals or for the one who has been killed accidentally by falling into a well or for the one killed in a mine. And one-fifth of Rikaz (treasures buried before the Islamic era) is to be given to the state."

The Prophet (ﷺ) said, "There is no Diya for a person injured or killed by an animal (going about without somebody to control it) and similarly, there is no Diya for the one who falls and dies in a well, and also the one who dies in a mine. As regards the Ar-Rikaz (buried wealth), one-fifth thereof is for the state."
