What is the ruling on publishing beneficial books that do not contradict Islamic Sharia on Amazon, which contains harmful and forbidden books, and earning money from this work, knowing that the site publishes in infidel countries and the books are published in English and may be purchased by both Muslims and disbelievers? And will I be sinful if a disbeliever reads it and benefits from it in a worldly matter? And what are the types of books that can be published on this site?

There is no objection to publishing books on the aforementioned website and benefiting from its earnings, as long as the subject matter of the books is beneficial, whether a Muslim or a non-Muslim benefits from them. In fact, books that invite to Islam should be placed there. As for the presence of some corrupt books or immodest pictures, this does not prevent benefiting from it due to the widespread nature of such issues. Those who access the site should fear Allah and avoid looking at what is impermissible.
