What is the ruling on dealing with Zitouna Bank, which adopts murabahah with a fixed profit margin or a percentage of the original acquisition cost?

A Murabaha contract is a sale at the initial price of the commodity with a known profit margin. It is permissible by scholarly consensus as long as the price and profit are known to both contracting parties. However, ruling on a Murabaha transaction with a specific bank depends on knowing the terms of the contract and the nature of the transaction.
