What is the ruling on profits generated from advertisements whose nature of work I do not know (whether it is permissible or forbidden)? And what is the ruling on writing about matters related to financial transactions (such as bonds and gold) given that their sources are foreign?

It is impermissible to publish advertisements for companies or places where forbidden acts are committed, such as places where alcohol is consumed, dance halls, and usurious banks. Advertisements must also not include impermissible elements, such as images of unveiled women or music. Articles must be beneficial and not contain anything that contravenes Islamic law. It is obligatory to learn the rulings of Islamic law concerning economic matters and to clarify them to people. It is not permissible to speak without knowledge.
