What is the ruling on accounting tasks related to usurious banks, such as creating interest-bearing deposits and withdrawing them, assisting in the procedures for employee or company loans, and recording the accounting interest for loans?

It is forbidden to cooperate in any activity connected to usury (riba), whether it is lending, borrowing, or depositing, based on the Almighty's saying: "And do not cooperate in sin and aggression." The aforementioned activities are prohibited, except for what relates to releasing the deposit and withdrawing the principal amount deposited only, without the interest; otherwise, that too would be forbidden. You must limit yourself to permissible activities. If you are unable to do so, you must leave this job and search for another, for whoever abandons something for the sake of Allah, Allah will compensate him with something better, and "Whoever fears Allah – He will make for him a way out And will provide for him from where he does not expect."
