Musnad Abu Ya'la al-Mawsili 155:232

Zakariya ibn Yahya al-Wasiti narrated to us, Hushaym narrated to us, from Mansur, from Ibn Sirin, from Abu Hurayrah, from the Prophet (may Allah bless him and grant him peace), who said: "The animal (al-'ajma')—its injury is 'jubar' (uncompensated), and the well is 'jubar', and the mine is 'jubar', and in the buried treasure (al-rikaz) is one-fifth."
