A testamentary appointment¹ is valid only for a specific act of disposal that the testator himself controls—such as paying his debts, distributing the discretionary one-third of his estate, or managing the affairs of his young children. It is invalid with respect to matters outside his authority, for example a woman’s attempt to appoint someone to oversee the property of her minor children and the like.
A person who is appointed for a particular matter does not thereby become executor for anything else.
If, after the executor has made the distribution, a debt surfaces against the deceased that absorbs the whole estate, the executor is not held liable. And if the testator says, “Put my one-third wherever you wish,” it is unlawful for the executor or for his own child to take it.
When someone dies in a place where there is neither a judge nor an appointed executor, any Muslim present may take charge of the estate and act in whatever way is most beneficial at the time—selling property and so forth.²
