FAQQuestions

What business area does Halal Equity Screening belong to?

Halal Equity Screening sits in the Treasury Markets and Sukuk business area — Islamic treasury, liquidity and Sukuk markets, built on ownership of real assets rather than interest-bearing instruments. It follows the BIAN Assess functional pattern over the Equity Screening Result asset, with the Equity Screening Result Assessment as its control record.

How is this isolated from conventional banking?

Completely. The Islamic landscape shares no code, repositories, namespaces or events with the conventional platform. This domain lives in the isb-treasury namespace with an isb-* repository and com.bank.islamic package, so the two can never mix by accident.

Is this a certified Shariah-compliant product?

No. It is an educational reference implementation in the BIAN service-domain style. Actual Shariah compliance of any real deployment requires certification by a qualified Shariah Supervisory Board. Standards referenced: AAOIFI, IFSB, IIFM.
