Are the returns on investment certificates from Faisal Islamic Bank of Egypt considered permissible (halal), especially given the differing scholarly opinions regarding them and the doubts raised by some concerning the bank's adherence to Sharia?

Investment certificates are of two types: investment certificates with a guaranteed fixed return, which are considered a loan with interest and are thus forbidden usury (riba). In this case, the saver gives money to the bank to receive it back with added interest, which falls under the Almighty's saying: "But Allah has permitted trade and forbidden interest."

The second type is investment certificates with an unguaranteed return. These are considered a legitimate Mudarabah (profit-sharing) contract, where the owner of the money gives it to the bank to invest in lawful projects in exchange for a percentage of the profit, without guaranteeing the principal or a fixed profit. This type is permissible.

It is necessary to ascertain the type of certificate and its conditions and to present it to a specialized scholar to ensure its compliance with Sharia regulations.
