What is the ruling on working for a company that manages social media pages for companies or public figures, where these pages might publish pictures of girls with their hair uncovered, or pictures of clients with female artists? And is it permissible to allow the client to publish pictures that I myself do not wish to publish?

The ruling on working in page administration depends on the nature of their content according to Sharia (definition). If the pages publish matters forbidden by Sharia, such as pictures of unveiled women, then it is not permissible to assist in them, due to the Almighty's saying: "And do not cooperate in sin and aggression." If a page contains forbidden things, one should refrain from administering it, and it is obligatory to stipulate to the page owners that forbidden things should not be published. If the majority of a page's content is forbidden, then it is not permissible to work in its administration, even if the administrators do not directly publish those forbidden things.
