FAQQuestions

What business area does Income Purification belong to?

Income Purification sits in the Shariah Governance and Compliance business area — the mandatory Shariah-governance layer that supervises, audits and evidences compliance across every Islamic banking line. It follows the BIAN Process functional pattern over the Purification Entry asset, with the Purification Entry Procedure 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-governance 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.
