What is the priority between the manumission of a slave and a bequest made to that same slave if both exceed one-third of the estate?

Primary text

If the manumission of the slave (whether a Mudabbar or a bequeathed slave) and the bequest to him collectively exceed one-third of the estate, the manumission takes precedence because it is more beneficial to the slave. The justification is that the master made a valid bequest concerning his own slave, and thus the manumission takes precedence over any wealth the slave might receive through the bequest, similar to the case where a share of the estate is bequeathed to a slave who is still in bondage.
