What was the advice of Prophet Muhammad (saw) regarding the payment of blood money if somebody dies in a mine or in a well or is killed by an animal?
 Narrated Abu Huraira:                     Allah's Apostle said, "No bloodmoney will be charged if somebody dies in a mine or in a well or is killed by an animal; and if somebody finds a treasure in his land he has to give one-fifth of it to the Government."
