Why AAOIFI vs lighter screens. Dow Jones Islamic and S&P Shariah indices allow up to 33% debt-to-market-cap, which lets in many companies that classical Islamic jurisprudence would exclude. AAOIFI Standard 21's stricter 30% debt-to-assets threshold reflects classical scholarship, stocks that pass it are accepted by Saudi, Emirati, and Malaysian Sharia boards. invest-like uses AAOIFI specifically because the looser screens admit borderline cases that defeat the purpose of a halal screen for most observant investors.
Important caveats. This is an automated educational screen against documented AAOIFI criteria, not a religious fatwa. AAOIFI thresholds can change; some scholars apply additional qualitative tests (debt purification, dividend purification) beyond the four quantitative criteria above. Always verify with your local scholar before treating any stock as halal-compliant for your specific purposes.
How invest-like measures this
invest-like applies the AAOIFI Standard 21 screen: the strictest of the mainstream halal screens. It tests three quantitative criteria (debt ratio, interest-bearing income, illicit-business revenue) plus a qualitative business-activity test. A stock is classified HALAL only if it passes all four.
AAOIFI thresholds are stricter than the Dow Jones Islamic and S&P Shariah indices on purpose: they reflect classical Islamic jurisprudence, not lighter Western Sharia indices that allow up to 33% debt-to-equity. Stocks that pass the AAOIFI screen are accepted by most Saudi, UAE, and Malaysian Sharia boards. Always verify with your local scholar; this is an educational screen, not a fatwa.
