What is the ruling on promoting a website that uses AdSense advertisements in exchange for an agreed-upon income, and earning from the Arab Computing Platform and the Gulf Center?

The answer to both questions revolves around the permissibility of the website's field of work and the service or benefit from which profit is generated within the platform and center. If the website is based on permissible matters, then promoting it is not forbidden, even if it displays advertisements, some of which are permissible and some are not. Likewise, if the service or benefit from which one profits through the platform or center is permissible, then there is no blame on him, even if the platform or center also offer other impermissible services.
