FAQQuestions

What is Qard Hassan?
Qard Hassan is a benevolent, interest-free loan repaid at exactly the amount borrowed. It is used for welfare and short-term need, never to earn a return for the lender.
What business area does Qard Hassan Account belong to?
Qard Hassan Account sits in the Deposits and Investment Accounts business area — Shariah-compliant deposit and investment accounts, where returns come from profit-sharing and safekeeping rather than interest. It follows the BIAN Fulfill functional pattern over the Qard Hassan Account asset, with the Qard Hassan Account Fulfillment Arrangement 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-deposits 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.
