What is the ruling on working as a website developer for a company that operates in the stock market and provides speculative services, knowing that the nature of the work does not involve speculation itself, but rather building and maintaining websites that facilitate the process of speculation for others?

If unlawful practices and disregard for Sharia (definition) regulations dominate a company's activities, it is not permissible to work there, even in the field of design, due to the involvement in assisting in sin, in accordance with the Almighty's saying: "And do not cooperate in sin and aggression." The aforementioned company, which facilitates speculative transactions, makes it difficult to avoid prohibitions within it. So, if unlawful elements and the commission of prohibited acts prevail in its dealings, then working for it is not permissible.
