What is the ruling on working for a company that deals with usury? Do the degrees of sin in it differ? Is the money earned from this work considered unlawful? And what are the consequences of leaving such a job for someone who would be harmed by that?

A company borrowing with usury is a major sin, the prohibition of which is agreed upon. Its owners must repent and rid themselves of these loans. It is not permissible to work for the company if the work is related to usurious loans, such as collecting them, repaying them, writing them, or witnessing them, except in cases of dire necessity. However, if the work is not related to usurious loans and the company's activities are permissible, there is no harm in working for it.
