It was narrated from Abu Hurairah that the Messenger of Allah P.B.U.H said: "The camels on which the dues (i.e., Zakat) were not paid will come, trampling their owners with their hooves. And cattle and sheep will come and trample their owners with their hooves and butt them with their horns. And hoarded treasure will come in the form of a baldheaded snake, and will meet its owner on the Day of Resurrection. Its owner will flee from it two times, then it will come to him and he will flee again, and will say: 'What do I have to do with you?' and it will say: 'I am your hoarded treasure, I am your hoarded treasure.' He will try to shield himself with his hand and it will devour it." (Sahih)
