Musannaf Ibn Abi Shaybah

Hazrat Ibn Jurayj states that I asked Hazrat Ata regarding a slave who intentionally killed another slave, while the murdered slave was better than the killer. What will be the ruling in this case? He replied: The master of the murdered slave will only receive the killer slave; he will not get anything else besides this. And Hazrat Amr bin Dinar, in response to this, said: He will only receive the killer of his slave; if he wishes, he may kill him, and if he wishes, he may keep him as a slave.
