Maliks Muwatta Book 44, Hadith Number 2E.
Section : Swearing for Blood-Revenge in Cases Involving Slaves.
Yahya said that Malik said, “What is done in our community about slaves is that when a slave is struck intentionally or accidentally and the master brings a witness, he swears with his witness one oath and then he has the value of the slave. There is no swearing for revenge in slaves, accidentally or intentionally, and I have not heard any of the people of knowledge say that there was.”
Malik said, “If a slave is killed intentionally or accidentally, the master of the slave who is slain has no swearing or oath. The master cannot demand his right except with a fair proof or a witness if he swears with one witness.”
Yahya said that Malik said, “This is the best of what I have heard on the matter.'”
