Maliks Muwatta Book 43, Hadith Number 8B.

Section : The Blood-Money for Injuries to Slaves.

Yahya related to me from Malik that he had heard that Said ibn al-Musayyab and Sulayman ibn Yasar said, “The head wound of the slave in which the bone is bared is a twentieth of his price.”

Malik related to me that he had heard that Marwan ibn al-Hakam gave a decision about a slave who was injured that the person who injured him had to pay what he had diminished of the value of the slave.

Malik said, “What is done in our community is that for the head wound of a slave that bares the bone, there is a twentieth of his price. The head wound which splinters the bone is three twentieths of his price. Both the wound to the brain and the belly wound are a third of his price. Besides these four, any other types of injury that decrease the price of the slave are considered after the slave is better and well, and one sees what the value of the slave is after his injury and what his value whole was before he had the injury. Then the one who injured him pays the difference between the two values.”
