Sayyiduna Abu Huraira (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The injury caused by an animal (or a person dying as a result of it) will be without compensation, death by falling into a well will be without compensation, death by falling into a mine will be without compensation, and payment of one-fifth is obligatory in the case of buried treasure (rikaz)." Ibn Shihab states: The word used in this hadith, al-jabar, means its blood will be without compensation, and the word al-ajma’ means animal. Shaykh Abu Bakr Nishapuri says: To my knowledge, apart from Yunus bin Yazid, no other narrator has mentioned that it is transmitted from Ubaydullah bin Abdullah in its chain of narration.
