What is the ruling on the salary received by an employee who has been working for the National Post Authority for 20 years, knowing that the Authority invests depositors' money in usurious banks and the stock market? And what should he do regarding the interest-free loan he takes from the Authority, knowing that the peer support fund from which the loan is deducted invests in conventional banks?

It is not permissible to work in usurious transactions or to record them. Thus, an accountant who signs and approves usurious contracts receives a haram (definition) (unlawful) salary, as the Prophet, peace and blessings be upon him, said: "Allah has cursed the who consumes Riba (usury), the one who feeds it, its two witnesses, and its scribe." He added: "They are all alike." However, if you were unaware of the impermissibility of the work, there is no blame upon you regarding the salary, but you must repent from it. If your work involves directly engaging in and recording usurious contracts, it is not permissible for you to remain in it after becoming aware of its impermissibility, unless you are in dire need of it. In such a case, you may remain only as long as the need persists, while striving to find another job. As for a qard hasan (definition) (good loan) to an employee without usurious interest, there is no harm in it, provided that any deducted fees are actual and not a trick to disguise usury.
