Yahya related to me from Malik from Ibn Shihab from Said ibn al-Musayyab and Abu Salama ibn Abd ar-Rahman from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "The wound of an animal is of no account and no compensation is due for it. The well is of no account and no compensation is due for it. The mine is of no account and no compensation is due for it and a fifth is due for buried treasures." (Al-kanz: see Book 17).
