What is the ruling on a millionaire's testimony, knowing that it is affiliated with an Islamic bank?

The ruling on the Millionaire Certificate is a branch of understanding its reality and the conditions for its eligibility with the aforementioned Islamic bank. The mere fact that the bank raises the banner of Islamization does not mean that all its transactions are permissible; rather, they must be presented to the controls of Sharia. Previous fatwas have been issued regarding the Millionaire Certificate issued by some usurious banks to attract customers. For more information, please refer to fatwas number 38093 and 71572.
