The Halal Investing Guide
This is the guide I wish existed when I first tried to figure out what "halal investing" actually means beyond the headline idea of "no alcohol, no gambling." Most explanations either stop at that one sentence or jump straight into Arabic finance terminology without ever showing the actual math. This one doesn't do either. By the end, you should be able to look at any public company, run the same three-question test a real Islamic index fund runs, and explain to someone else exactly why a stock passes or fails — not just repeat that it does.
What this guide is, in one paragraph
Halal investing applies a real, documented screening standard — the one actual Islamic index funds and Shariah-compliant ETFs use — to public companies, checking both what a company does and how it's financed. It is not a vibe check. It is not "avoid tech, buy gold." It is a specific, repeatable test with specific numeric thresholds, and once you understand the test, you can run it on any company yourself.
Why debt and interest are the center of this, not a footnote
Here's the plain-language version. In Islamic finance, charging or paying ribaRiba is the Arabic term for interest or usury — a predetermined return on a loan, charged regardless of whether the borrower's venture actually succeeds. It's prohibited because it separates return from real economic risk-taking. — interest, essentially — is considered exploitative and forbidden, because it guarantees the lender a return regardless of whether the borrower's business actually succeeds. Compare that to buying a share of a real company: your return depends entirely on whether that business does well. That's the whole philosophical spine of halal investing — profit should come from shared risk in a real, productive enterprise, not from a guaranteed, risk-free return on money itself.
That single idea is why almost every rule below exists. Conventional banks and insurers are excluded because their entire business model is interest. Heavily indebted companies are flagged because too much of their capital structure runs on interest payments, even if their products are perfectly fine. And a company sitting on a pile of cash earning interest in a bank account has to account for that too. It all traces back to the same root idea: money shouldn't make money by itself.
The three questions every halal investing decision comes down to
Strip away the terminology and a real Shariah stock screen is just three questions, asked in order. If a company fails any one of them, it's out — you don't need to ask the rest.
What does the company actually do?
The business-activity screen. If the core business is conventional banking, alcohol, gambling, tobacco, pork, adult content, weapons, or conventional insurance, it's excluded immediately — no ratio can save it.
How much debt does it carry?
The leverage test. Interest-bearing debt divided by the company's total market value has to stay under 33%. A great, "clean" business can still fail here if it's financed with too much conventional debt.
How much sits in interest-bearing cash?
The cash test. Cash and interest-bearing securities divided by market value also has to stay under 33%. A company hoarding cash in interest-bearing accounts fails this even if it has zero debt.
A fourth, less mechanical check usually follows: impermissible income — revenue from incidental non-compliant sources (like ad revenue that happens to serve an alcohol brand) — is generally capped around 5% of total revenue. This one is the hardest to verify from public data, which is exactly why you'll see "questionable" verdicts later in this guide rather than a forced pass or fail.
Try it yourself: the ratio test, live
This is the exact math from questions 2 and 3 above. Drag the sliders to represent a hypothetical company's debt and cash, each as a percentage of what the whole company is worth (its market capitalization), and watch the verdict update in real time. This is precisely what happens when you or a screening service runs a real company's numbers.
The categories that are automatically out
Before any ratio is even calculated, a company's core business is checked against this list. If its main line of business falls into any of these, it's excluded — permanently, not conditionally.
| Category | Why it's excluded |
|---|---|
| Conventional banks & lenders | Their entire revenue model is charging and paying interest — the exact thing this whole framework exists to avoid. |
| Conventional insurance | Traditional insurance involves elements of uncertainty (gharar) and interest-based reserve investing that most scholars treat as impermissible; Islamic cooperative insurance (takaful) exists as an alternative. |
| Alcohol | Production, distribution, or a core business built around alcohol sales. |
| Gambling | Casinos, sports betting, and lottery operators — profit derived from games of pure chance. |
| Tobacco | Production and sale of tobacco products. |
| Pork products | Production, processing, or sale of pork as a core business. |
| Adult content | Any core business built around adult content. |
| Weapons manufacturing | Conventional and controversial weapons production; some screens treat defense-adjacent revenue as a gray area rather than a hard exclusion — this guide treats it as one to flag, not automatically fail. |
Purification: the step almost every beginner guide skips
Even a stock that passes cleanly can generate a tiny bit of impermissible income — usually interest earned on the company's own cash reserves. The fix isn't to avoid the stock; it's purification: figure out roughly what share of the company's income came from that interest, and donate that same share of any dividend you receive to charity, rather than keeping it. If you don't receive a dividend (true for every growth stock in the list below — none of them currently pay one), there's nothing to purify yet, but the moment one starts paying a dividend, this is the step that keeps your return actually clean rather than just approximately clean.
Real Sharia-compliant growth stocks: a live top 10
Rather than build a screen from scratch and ask you to trust my math, here's a fully verifiable shortcut: the ten largest holdings, by weight, of SPUS (SP Funds S&P 500 Sharia Industry Exclusions ETF) — a real, actively traded, AAOIFI-screened exchange-traded fund. These aren't picks I'm making; they're the actual top holdings of a real fund whose entire mandate is holding only screened, compliant, large-cap U.S. companies. You can look this list up yourself and get the same answer.
Weights as of the most recent published SPUS holdings data (stockanalysis.com), and will drift over time as the fund rebalances and prices move — treat these as directionally representative, not as live, minute-by-minute weights. These ten holdings together represent roughly 56% of the fund's total portfolio. Full holdings and methodology are published by SP Funds.
How to actually invest halal
Understanding the test is step one. Here's what to actually do with it, in the order most beginners should approach it.
Start with a dedicated Sharia-compliant fund, not individual stock-picking
Funds like SPUS, HLAL (Wahed FTSE USA Shariah ETF), or SPWO/ISWD-style global Islamic index funds already run the business-activity and ratio screens continuously and rebalance when a holding stops qualifying. For a beginner, this is the lowest-effort, most reliable starting point — you inherit a maintained screen instead of re-deriving it yourself every quarter.
If you want individual stocks, use a screening app before you buy
Services built specifically for this — Zoya, Musaffa, and IdealRatings are the most commonly referenced — run the same activity and ratio tests on individual tickers and keep the data current. Use the interactive calculator above to understand why a stock passes or fails, then use a maintained tool to check the live numbers, since balance sheets change every quarter.
Re-check your holdings periodically, not just once
A company that passes today can take on debt next year and fail the ratio screen at the next rebalance. Real Islamic index funds re-screen constituents quarterly for exactly this reason. Treat compliance as a status that needs re-confirming, not a permanent label.
Purify dividend income, don't just skip it
If a compliant holding starts paying a dividend, estimate the share of company income that came from interest (usually disclosed or estimable from the balance sheet) and donate that share of your dividend to charity. This keeps the income you actually keep clean, rather than assuming a passing stock means every dollar it pays you is automatically clean too.
Don't confuse "halal" with "ethical" or "ESG"
They overlap sometimes, but they're different tests measuring different things. A halal screen says nothing about labor practices, environmental impact, or executive pay — an ESG-labeled fund can hold conventional banks and heavily leveraged companies that would fail a halal screen outright, and a halal-compliant company can still score poorly on unrelated ESG criteria. Treat them as separate lenses, not synonyms.
Test yourself
Five questions. No time limit, no login. If you can get through these without missing more than one, you understand this better than most people who casually use the word "halal stock" without ever having run the actual test.

Methodology & sources
Screening standard. AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions)-style business-activity exclusions plus the commonly cited 33% / 33% / 5% financial-ratio thresholds, the same framework a close variant of which underlies most major Shariah-compliant index products (S&P Shariah, MSCI Islamic, Dow Jones Islamic Market). This is one widely used framework among several; a different Shariah board could apply different thresholds or a different debt definition and reach different verdicts on borderline names.
Top-10 stock list. The ten largest holdings of SPUS (SP Funds S&P 500 Sharia Industry Exclusions ETF) by portfolio weight, sourced from stockanalysis.com's SPUS holdings page and the fund's own published materials at sp-funds.com. This is a real, third-party, continuously screened fund's actual composition, not a screen I derived myself.
Ticker screener dataset. Market capitalization from Massive Market Data (real-time reference data). Long-term debt and cash figures for the 26 covered tickers are drawn from each company's most recent full-year balance sheet as compiled in AEA's own 3-statement models, sourced from public filings. The debt figure used is long-term debt & capital leases only — several companies' short-term liabilities mix true short-term debt with non-debt items like deferred revenue that isn't cleanly separable in the underlying model data, so this scope makes every debt ratio here a conservative, likely-understated estimate rather than an overstated one. Similarly, the cash figure is cash & equivalents only, not short-term investments, making the cash ratio conservative as well.
Impermissible income. Not computed as a percentage for any name in the ticker screener. Segment- or category-level revenue data at the resolution the 5% test requires (ad-category mix, content-library breakdowns, etc.) generally isn't public, and presenting an invented number as if it were real would be worse than not presenting one. Where that gap is the deciding factor, the tool's verdict is "questionable," not "pass."
Not a fatwa. This guide and the tools on this page are a personal, educational explanation of a documented, publicly available screening standard, written by someone who is not an Islamic scholar and not qualified to issue religious rulings. Anyone with religious questions about their own investments should consult a qualified Shariah advisor. Different scholars and different Shariah boards can and do reach different conclusions on genuinely borderline names.
Not investment advice. Nothing on this page is a recommendation to buy, sell, or avoid any security. The stock list above describes what a real fund currently holds, not a personal recommendation from this site.
