Is a previously made will valid if a slave or similar person gains freedom before death without changing the will?

Primary text

If such an individual is manumitted and then dies without altering their previous will, the will is valid. This is because they subsequently possess full legal capacity and a sound legal standing (*qawl sahih*). Their only deficiency while enslaved was the lack of property, and a will is valid even in the absence of property, analogous to a poor person making a will and later acquiring wealth.
