Q: Is a mortgage always riba? A: Structures vary — some conventional mortgages are interest-based loans, while some providers offer alternative structures (such as diminishing partnership or lease-to-own models) intended to avoid interest. Whether a specific product achieves that in practice is a scholarly question about its actual contract, not something to assume either way.

Q: Can I use a credit card if I always pay the full balance and never incur interest? A: Scholars hold different views on this, partly because the underlying agreement may still technically involve an interest clause even if you never trigger it in practice. This is a genuine area of differing qualified opinion — ask a scholar you trust rather than assuming a single universal answer.

Q: What about student loans or other loans that may be unavoidable in some circumstances? A: Necessity and hardship are real considerations scholars weigh carefully, and views differ by circumstance and jurisdiction. If you're facing this decision, bring your specific situation to a qualified scholar rather than trying to resolve it from general reading alone.
