Is it permissible to work in the field of information technology for a company that sells permissible and impermissible products online, knowing that the work is not directly related to the sale and purchase of impermissible items, and that the information technology team is unaware of the true nature of the impermissible products offered?

It is permissible to work in companies with mixed activities (permissible and dominant) under certain conditions: that the original activity of the company is permissible, that the product offered by the company is not specifically for something forbidden or predominantly used for it, and that the employee does not directly engage in the forbidden work himself.
