What is the ruling on working for an institution that deducts sums of money from employees' salaries to save and disburse them to them later, if this institution invests its money in activities that may be unlawful, and is this work considered a form of aiding in sin and aggression?

The fundamental principle regarding social insurance provided by the state is permissibility, and therefore, the fundamental principle regarding working in it is also permissibility. If some of its operations are impermissible, such as depositing funds in interest-based banks, this does not render working in it impermissible, as long as the worker does not perform the impermissible act but rather performs permissible acts. It is permissible to work in companies where permissibility is predominant, even if some of their activities are impermissible, provided that the product is not designated for an impermissible purpose or predominantly used for it, and that the employee does not directly engage in the impermissible act himself. It is incumbent upon the layperson to follow the guidance of trustworthy and knowledgeable muftis and to disregard obsessive doubts.
