Shibui Finance is a free halal stock screener, also called an Islamic stock screener, that you run by talking to Claude. Most halal screeners check one ticker at a time and return a pass/fail verdict. Shibui screens the entire market at once and lets you describe exactly what you want: "find AAOIFI-compliant stocks with revenue growth above 15% and a P/E under 25." It checks the three compliance ratios against live quarterly filings for nearly 10,000 US companies and applies your filters in the same request. No app to install, no formulas to maintain.
The difference is the question each tool answers. A dedicated app tells you whether a stock is halal. Shibui tells you which halal stocks are worth a closer look, because it combines compliance with the same financial analysis you would run on any other investment.
What a halal stock screener checks
Halal screening, also called Islamic or Shariah screening, has two parts. The first is the company's business. Firms that earn their primary revenue from alcohol, gambling, tobacco, weapons, adult content, or conventional banking and insurance are excluded no matter how their balance sheet looks. Sector and sub-industry classifications handle most of this, with judgment needed for mixed cases like a hotel group that also runs casinos.
The second part is financial ratios. A company in a permissible industry can still fail if it carries too much interest-bearing debt or earns too much from non-permissible sources. AAOIFI Standard No. 21 sets three thresholds: interest-bearing debt under 30% of market capitalization, interest-bearing securities and cash under 30%, and non-permissible income under 5% of revenue. Many retail screeners swap market cap for total assets and use a 33% threshold, which stays steadier because it does not move with the daily share price. Shibui has both denominators in the database, so you pick the standard and it computes the ratios that way.
Screen the whole market, not one ticker at a time
Checking compliance ticker by ticker is fine when you already have a shortlist. It does not help you build one. Shibui runs the AAOIFI ratios across every US equity in the database in a single pass, so you start from the full compliant universe rather than a name you happened to think of.
"Screen all US stocks for AAOIFI compliance using total assets as the denominator. Keep those with debt-to-assets under 25%, positive free cash flow in each of the last four quarters, and a market cap above $2B. Exclude alcohol, gambling, tobacco, and weapons sectors."
Claude applies the sector exclusions, computes the ratios from the latest filings, and returns the names that pass with their supporting numbers. One request, one list.
Add your own investment criteria
Compliance is the floor, not the decision. Within the compliant universe, stocks range from speculative to high quality, and a verdict alone does not separate them. Because Shibui is a general financial screener, you can rank compliant stocks by whatever matters to you.
"Among AAOIFI-compliant stocks, score each one: +1 for revenue growth over 12%, +1 for gross margin over 40%, +1 for a net cash position, and +1 for a 5-year revenue CAGR over 10%. Show the stocks scoring 3 or 4, sorted by score."
You define the scoring. Change the weights, add a criterion, tighten a threshold, and the screen adapts. For a step-by-step walkthrough of building these screens, see the guide on screening halal stocks with AI.
Track compliance across quarters
Compliance is not permanent. A leveraged acquisition can push debt over the line; parking cash in interest-bearing accounts can lift non-permissible income. A current snapshot hides that history.
"For Microsoft and Broadcom, show interest income as a share of revenue and debt-to-total-assets for each quarter since 2022, and mark any quarter that crossed the 33% line."
Claude pulls the actual quarterly values and checks each period, so a company that has sat well below the threshold for years reads differently from one that only dipped under it last quarter.
How it compares to dedicated halal apps
Apps like Zoya and Musaffa are built for halal investing and do things Shibui does not: instant single-ticker verdicts, purification and zakat calculators, ETF look-through, compliance alerts, and curated baskets, all with no setup. For a quick "is this halal?" check on your phone, they are the better tool.
Shibui is a data tool, not a halal app. It fits better when you want to screen the full market by compliance plus your own criteria, build a custom ranking, or test how a compliant strategy held up historically. The two work well together: an app for daily checks, Shibui for research. A fuller side-by-side is on the Shibui vs Zoya page.
What it cannot do
Shibui does not issue halal or haram rulings. It provides the financial data and the ratios; you apply the standard you follow and draw the line. Scholars differ on thresholds and denominators (AAOIFI, DJIM, MSCI, and FTSE all vary), and ambiguous business-activity cases may need scholarly review. There is no purification or zakat calculator and no Shariah board certification.
The data is end-of-day, US equities only (NYSE and NASDAQ), from tier-3 providers. It is solid for screening and research but is not institutional grade and not meant for regulatory use. Coverage and refresh details are on the data sources page.
