What is the ruling on working at Arab Bank?

Working in interest-based (usurious) banks is absolutely forbidden, due to its involvement in consuming usury, writing it down, bearing witness to it, or assisting in it. This prohibition includes all jobs, even security, cleaning, and service. The Arab National Bank is an interest-based bank, and it is not permissible to deal with it except according to the regulations of legitimate Tawarruq, whereby the customer takes possession of the commodity himself, does not appoint the bank as an agent, and does not sell to the same exhibition from which the bank purchased. It is advisable to deal with Islamic banks whenever possible.
