We do not have any information about the system used in the bank mentioned. We have come across a question directed to Dr. Muhammad al-‘Usaymi (may Allah preserve him) about the ruling on working in the Saudi Bank in Branch Administration, and which banks is it permissible to work in? He replied: Rather this bank is riba-based, and it has an Islamic service. It is not permissible for you to work except in that which has a connection to the Islamic service, with the stipulation that you must adhere to the statements of the sharee’ah council. May Allah help and guide you. End quote from the shaykh’s website.
And Allah knows best.
