Malik related to me that he heard that Umar ibn Abd al-Aziz gave a judgement about the mudabbar who did an injury. He said, "The master must surrender what he owns of him to the injured person. He is made to serve the injured person and recompense (in the form of service) is taken from him as the blood-money of the injury. If he completes that before his master dies, he reverts to his master."
