Shibui Finance lets you screen for halal-compliant stocks by asking Claude in plain English. Instead of looking up tickers one at a time for a pass/fail verdict, you describe what you want: "find AAOIFI-compliant stocks with revenue growth above 15% and positive free cash flow." Claude checks the actual financial ratios (debt-to-assets, interest income as a share of revenue) against live quarterly data for nearly 10,000 US equities. No app download, no formulas.
You connect Shibui to Claude once (free plan works), and every conversation after that can run halal compliance checks alongside any other financial analysis. Screen the whole market, check a specific ticker, or combine compliance with your own investment criteria.
What makes a stock halal
Shariah compliance screening has two parts. The first is business activity: companies that derive primary revenue from alcohol, gambling, tobacco, weapons manufacturing, pornography, or conventional banking and insurance are excluded regardless of their financials. GICS sector and sub-industry codes help with this screen, though edge cases exist (hotel chains with casino operations, beverage companies that mix alcohol and juice lines).
The second part is financial ratios. Even a company in a permissible industry may carry too much interest-bearing debt or earn too much income from non-permissible sources. AAOIFI Standard No. 21 defines three quantitative thresholds that a company must pass. These ratios are the core of halal stock screening.
The three AAOIFI financial ratios
The formal AAOIFI standard sets three thresholds: interest-bearing debt below 30% of market capitalization, interest-bearing securities and cash deposits below 30% of market capitalization, and non-permissible income below 5% of total revenue. Many retail screeners (Zoya, Musaffa, HalalScreener) use a modified version that replaces market cap with total assets as the denominator and applies a 33% threshold instead of 30%. The total-assets approach is more stable because compliance does not shift with daily stock price fluctuations.
Shibui has both denominators available in the database. The quarterly financials contain total assets, debt, interest income, revenue, accounts receivable, and cash. The valuation table carries daily market capitalization. The user chooses which standard to apply, and Claude computes the ratios from whichever denominator you specify.
Beyond pass/fail: screening halal stocks by criteria
Existing halal screeners answer one question: "Is this stock halal?" That is useful, but it is only the starting point. A pass/fail verdict tells you nothing about whether a company is growing revenue, generating cash, or trading at a reasonable valuation. Halal investors still need to find good investments within the compliant universe.
Most investors verify compliance on one tool, then manually transfer tickers to a separate screener or spreadsheet for analysis. Some maintain lists of hundreds of compliant stocks that they re-check quarterly.
"Find stocks where debt-to-total-assets is below 33%, interest income is less than 5% of revenue, and revenue grew more than 15% year-over-year. Exclude gambling, alcohol, tobacco, and weapons sectors. Show P/E, market cap, and free cash flow."
Claude checks the three financial ratios from the latest quarterly filings, applies GICS sector exclusions, and layers the growth filter on top. Companies that pass everything appear in the results with supporting metrics. One sentence in, structured results out. No switching between tools, no manual cross-referencing.
Building a composite halal investment score
A halal verdict is the floor, not the ceiling. Within the compliant universe, stocks range from speculative micro-caps to established compounders. Ranking them requires combining compliance with investment quality criteria.
"For AAOIFI-compliant stocks, score each on: revenue growth above 15% (1 point), EPS growth above 15% (1 point), positive free cash flow (1 point), P/E below 30 (1 point), and within 10% of 52-week high (1 point). Show stocks scoring 4 or 5 out of 5, sorted by score."
Claude computes each criterion from different data sources: financial statements for revenue and EPS growth, cash flow statements for FCF, the valuation table for P/E, and technical indicators for the 52-week high proximity check. It assigns points per criterion and ranks the results. This is not a preset filter. The user defines the scoring system. Change the weights, add criteria, tighten thresholds. The scoring adapts to whatever strategy the investor follows.
Tracking compliance changes over time
Compliance is not permanent. A company can cross the 33% debt threshold after a leveraged acquisition. Interest income can spike when a company parks excess cash in interest-bearing accounts. Revenue composition shifts as business lines grow or shrink.
"Check NVIDIA's debt-to-total-assets ratio and interest income as a percentage of revenue for each quarter over the past 3 years. Flag any quarter where either ratio crossed the AAOIFI threshold."
Claude retrieves the actual quarterly values from the financial statements and checks them against the thresholds per period. You see the trajectory, not just the current snapshot. A company that has been at 8% debt-to-assets for 12 straight quarters is a different proposition from one that just dipped below 33% last quarter after years above it. No existing halal screener shows this quarter-by-quarter compliance history.
What this cannot do
Shibui does not issue halal or haram verdicts. It provides the financial data; the investor applies their own interpretation. Scholars disagree on thresholds and denominators (AAOIFI, DJIM, MSCI, and FTSE standards all differ). The user decides which standard to follow and where to draw the line.
There is no dividend purification calculator or zakat calculator. Dedicated halal apps like Zoya and Musaffa handle those. There are no curated halal watchlists or pre-screened baskets. There is no Shariah board certification. The AAOIFI ratios are the quantitative portion of compliance; the qualitative assessment (detailed business activity review at the sub-industry level) may require scholarly consultation for ambiguous cases.
