Does brain death have the ruling of death, such that the estate is divided among the heirs?

Question:
He says: Honorable Shaykh, may Allah grant you success. Among the conditions is the confirmation of the death of the deceased, and the criterion for confirming his death. If a person is in a state of brain death and the specialized doctors agree that he has died brain-wise, is his estate divided even if the soul has not yet left the body? May Allah hasten [the answer].

Answer:
No, his estate is not divided, nor is he washed, shrouded, or prayed over until his soul has finally departed and nothing remains in him. Brain death does not establish the ruling of death until the soul leaves the body in a final departure.
