Is it permissible to use the black crow in hunting falcons and shahin hawks, and what is the ruling on purchasing it for this purpose?

It is permissible to own and sell the Abqa raven if it provides a lawful benefit without harm, such as hunting. The statements of scholars prohibiting its ownership and sale are interpreted to apply to instances where it is harmful and offers no benefit. It is known that the Abqa raven is among the "fawasiq" (noxious creatures) which are legislated to be killed.
