Abu Dawud Book 34, Hadith Number 4571.
Chapter : Bloodwit for unintentional murder which resembles intentional.
Narated By Abdullah ibn Amr ibn al-‘As : The Prophet (PBUH) said: Musaddad’s version has: He addressed on the day of Conquest. The agreed version then goes: Beware! Every object of pride of pre-Islamic times, whether it is blood-vengeance or property, mentioned or claimed, has been put under my feet except supply of water to the pilgrims and custody of the House (the Ka’bah). He then said: Beware! The blood-wit for unintentional murder, such as is done with a whip and stick, is one hundred camels, forty of which are pregnant.
