What is the ruling on working in the promotion of various products online, knowing that some of the originating websites may contain images of women who are immodestly dressed or advertisements that may lead to Sharia violations, and is it permissible to promote if the link does not directly lead to pages of violations?

There is no harm in creating a promotional and advertising website for products, programs, and goods that are permissible by Islamic law. This is no different from traditional renting or brokerage. Referring a client to the company's website does not prevent the work as long as the contract is for something permissible, unless the product display includes forbidden images or prohibited phrases, or if the website itself is pornographic, missionary, or among other sites from which one who enters them is not safe from their evils, or if the large number of visitors is considered a support for them. In this case, it is not permissible to refer to them even if the product is permissible, considering the outcomes and averting harm.
