Is money earned through the red mercury halal or haram?

Red mercury is controversial, and there is no confirmation of its existence. If its existence is proven and it has permissible benefits, then there is no objection to its sale and purchase, except for those who use it in magic and sorcery. Money earned from selling red mercury, if used in magic or fraud, is unlawful (haram), and it is not permissible to deal with its owner in any way concerning it. If your friend obtained this money through unlawful means, it is not permissible to accept it. Whoever sells something unlawful, such as selling grapevines to someone who will press them into wine, must donate its entire price as charity. And whoever's money is unlawful, it is not permissible to buy from him, nor eat his food, nor accept his gift.
