How is manumission treated if it is suspended upon a condition that occurs during the testator's final illness?

Primary text

If a master suspends the manumission of his slave upon a condition, and that condition is fulfilled while the master is in his final illness, the manumission is considered to be executed from the one-third of the estate. This was stated by Abu Bakr, and Ahmad held a similar view regarding divorce. This ruling is based on the principle that manumission during illness impacts the rights of the heirs to two-thirds of the estate, so it must be restricted to the one-third, like an immediate manumission.
