Is reviewing a company's financial statements that include loans and their interest, in addition to reviewing ordinary revenues and sales unrelated to loans, considered permissible work?

Reviewing and auditing the statements of usurious loans for the company is not permissible, as it is a form of assistance in usury and an endorsement of evil. Allah Almighty says: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression). The Messenger of Allah, peace and blessings be upon him, cursed the one who consumes usury, the one who feeds it, its two witnesses, and its scribe, and he said: "They are all equal."

Therefore, you must refrain from that and seek another job. It is not permissible for you to remain in this job unless you are compelled to support yourself and your family, in which case you may stay only as much as needed until you find a permissible job.
