Question 935) - What is the ruling of the transactions of a man with his own wealth if he is free and adult but silly and incompetent [safih]?

A: According to Imaam Abu Hanifa RAH. If a man has intelligence, has attained puberty, and is free, he may not be incapacitated. He is allowed to transact with his wealth, even if he wastes and destroys his wealth in something without purpose e.g. he throws his wealth into the sea or burns it.
