Is it permissible to use perfume extracted from ambergris that comes from the belly of a sperm whale, and is it pure (tahir)?

The carrion of the sea is pure, due to the saying of the Prophet, peace and blessings be upon him: "Its water is pure, its dead meat is lawful." The Companions ate ambergris, which is a sea carrion, and the Prophet, peace and blessings be upon him, approved them, saying: "It is a provision Allah has brought forth for you." Based on this, perfume extracted from ambergris is pure.
