AAOIFI is an important international reference for drafting and understanding Islamic banking contracts and governance, but it is not the regulatory body for Egyptian banks.
In Egyptian contexts, we use the AAOIFI standard to explain the Sharia compliance framework, then refer to the Central Bank of Egypt for regulatory rules and customer rights, and to the bank itself for the actual application of the contract, fees, and procedures.
The figures, fees and limits in this answer vary by bank and change over time — confirm them with your bank or the official source before acting.
