Is money earned from work that is permissible in Islamic law but forbidden by secular law considered halal or haram?

The fundamental principle is the permissibility of money earned from a lawful activity. As for a positive law prohibiting a certain action, the status of this law must be considered. If it serves a public interest and does not contradict Islamic law, then it must be adhered to, and it is not permissible to violate it, because it falls under the category of the ruler restricting what is otherwise permissible.
