What is the ruling on working for a company that provides maintenance and development services for IT networks and infrastructure to usurious institutions, knowing that the nature of the work does not directly involve usury, but rather facilitates communication for systems that may be used in usury, taking into account the difficulty of avoiding this in the country?

Your work at the company is permissible, but it is not permissible for you to carry out tasks related to an interest-based bank, such as installing cameras or communication networks. This is due to the prohibition of assisting in usury. Communication means are fundamental to the operation of a bank, and it is not permissible to cooperate in sin and transgression. If you are asked to do so, you must refuse, even if it leads to your dismissal. The paths to what is permissible are many, and whoever gives up something for the sake of Allah, Allah will compensate him with something better.
