Appointing a minor as a guardian, then his reaching maturity before the testator's death

Question:
He says: Honorable Shaykh, may Allah grant you success. If a guardian is appointed over a property, and at the time of appointment he was a minor, and then this minor grew up before the testator died, does he become the guardian?

Answer:
No. He does not become a guardian unless he is appointed after his maturity, after he reaches puberty. If he is appointed and entrusted after he reaches puberty, there is no harm.
