What is the ruling on a sick master emancipating his only slave, who is worth 100, after the slave caused an injury to the master resulting in a liability of 100?

Primary text
If the value of the slave is 100 and the master owes 100 for the slave's injury (Arsh), half of the slave is manumitted. The master retains half ownership of the slave and owes the remaining half of the slave's value to the freed portion. This calculation is based on the principle that the liability (Arsh) for the injury corresponds proportionally to the part of the slave that is freed. For example, if the slave is worth 100, and the liability equals the full value, half the slave is freed, and the liability is split accordingly.

If the slave's value were 200, one-fifth would be manumitted because the liability (100) equals half the value, meaning the remaining half of the value (100) is owed to the master. The remaining portion of the slave equals 150 (three-fifths), and the freed portion is 50 (one-fifth). If the value is 50 or less, the entire slave is freed because the liability of 100 equals or exceeds twice the slave's value.
