What is the ruling on working as a manager of a computer program that records all transactions of a car oil company, including usurious loan and deposit transactions and their interests, knowing that the manager's work is limited to supervising the program's performance and is not directly involved in recording those transactions, and that the number of accountants who record usurious transactions is small and the proportion of usurious data is small within the total entered data?

It is permissible for the accountant to work on the aforementioned program and benefit from what he earns from it, because the mentioned جزئية (specific part/component) is subordinate and not intended. This does not affect the ruling on general supervision of the company's program as long as its activity is permissible, and as long as one does not directly engage in what is forbidden nor intentionally or directly assist in it. What has been mentioned is among the matters that are widespread trials. However, transitioning to a permissible job with no ambiguity is among the commendable acts of piety. There is no obligation to dispose of the salary, but if one does so, it is an act of charity.
