Do all Islamic banks have to have identical products?

No.

Steps

1. Agreeing on Sharia principles and standards doesn't mean all banks offer the same contract, price, or operational details.

2. Two banks might use Murabaha financing, but their agency procedures, fees, documentation, and early repayment policies could differ.

3. Compare the product itself and its contract, not just the bank's name or the word "Islamic."

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.
