A Shariah Board is established within a financial institution and comprises specialists in Islamic law. It reviews the structure of proposed products, contractual documentation, and the procedure for conducting transactions, then issues a conclusion on their permissibility.

Its functions are not limited to initial approval: the board also performs subsequent monitoring to verify that actual practice conforms to the approved structure. The issue of income purification—excluding from results any proceeds deemed impermissible—is also examined separately.

The presence of such a board is a practical indicator that compliance with principles is ensured procedurally, rather than merely claimed for marketing purposes. However, there is no uniformity: conclusions from different boards on similar products may differ, since Islamic legal schools diverge on certain matters.

For clients, this implies a practical approach: focus not on the product's marketing designation, but on who issued the conclusion, whether it covers the specific product, and whether subsequent monitoring is conducted. In Uzbekistan, where the regulatory framework in this area is developing, such verification is all the more appropriate.
