Financial Foundations & Halal Investing
This is the learning path I wish existed before I ever tried to pick a stock. It begins with the material I helped teach at my mosque—bank accounts, credit-card statements, credit scores, borrowing, Roth IRAs, index funds, and diversification—then works toward halal investing and the actual screening math. By the end, a reader should be able to explain the financial structure underneath a decision, not just repeat a verdict from an app.
New research index
What would a transparent halal growth benchmark look like?
I built the AEA Halal Growth 50 to answer that question in public: 50 currently screened companies, nine sectors, a deliberate technology tilt, and an equal 2% starting weight for every constituent. It is a hypothetical student-built index, not an ETF and not available for investment.
What this guide is, in one paragraph
This guide now begins where the financial-literacy conversations I helped teach at my mosque began: with the accounts, bills, borrowing decisions, and investing structures people meet before they ever screen a stock. The second half applies a documented halal-investing framework to public companies, checking both what a company does and how it is financed. It is not a vibe check, and it is not “avoid tech, buy gold.” It is a progression from understanding money to deciding what kind of return you are willing to earn.

Part I · Financial foundations
Before asking what to invest in, know what is happening in your own account.
When I helped teach this material, we worked upward. Checking and savings came before credit cards. Credit cards came before credit scores and mortgages. Index funds and Roth IRAs came before individual stocks. Halal screening made more sense once the machinery underneath the decision was no longer mysterious.

01
Banking
Checking is for movement. Savings is for distance.
A checking account handles regular transactions: deposits, bills, debit-card purchases, and transfers. A savings account is designed to separate money you do not need for today’s spending. The practical lesson was not “one is good and one is bad.” It was to give every dollar a job and know which account is doing which job.

02
Credit cards
Minimum payment, statement balance, and current balance are not synonyms.
The minimum payment is the least the issuer requires by the due date to keep the account from becoming delinquent; it is not a recommended payoff plan. The statement balance is what the last billing cycle closed with. The current balance also includes transactions posted after that statement closed. Paying only the minimum usually means more interest and a much longer payoff. Missing the minimum by the due date can bring fees, contract consequences, and damage to credit history.

Credit scores
A score is a summary of a report, not a grade on your character.
There are multiple scoring models, but the habits are consistent: pay on time, keep revolving balances manageable relative to limits, avoid opening many accounts at once without a reason, keep older well-managed accounts when appropriate, and check credit reports for errors. Checking your own report does not hurt your score. A stronger history can affect whether a lender approves a mortgage and the rate offered, but income, assets, savings, existing debt, and the full report matter too.

04
Borrowing
A monthly payment can hide the total price.
A mortgage spreads the cost of a home across years, but the rate, term, down payment, taxes, insurance, and fees determine what the home actually costs. A bond turns the relationship around: the investor lends to a government or company in exchange for promised interest and principal repayment, while taking credit, rate, and inflation risk. In both cases, “Can I make the payment?” is a smaller question than “What obligation am I accepting, for how long, and at what total cost?”

05
Investing structure
The account, the investment, and the strategy are three different choices.
A Roth IRA is an account with specific tax treatment and eligibility rules; it is not itself an investment. An index fund is an investment product designed to track a market index, often by holding the securities in that index or a representative sample. Diversification spreads exposure, but it does not remove loss. A beginner has to decide where the money sits, what it owns, what fees apply, and how much volatility can be tolerated without abandoning the plan.

Values
Only now do we apply the halal screen.
Once the basic machinery is clear, the ethical question becomes sharper: what activity am I funding, how much interest-bearing debt is supporting it, where does its income come from, and what purification may be required? The screen below is one widely used framework—not the only scholarly view and not a substitute for a qualified religious advisor.
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 universe. Every current S&P 500 constituent plus every current S&P MidCap 400 constituent — 902 companies, sourced from two funds' own published daily holdings files (SPDR's SPY for large-cap, SPDR's MDY for mid-cap; both are State Street's live, daily-updated records of the actual indices, not lists I compiled or maintained by hand), spanning every sector on purpose, including banks, insurers, and defense contractors that are expected to fail. Because this comes directly from the funds' own holdings disclosures, it tracks real index membership changes automatically rather than going stale the way a manually maintained list would. On top of that, 71 more companies were added individually — smaller or newer names outside both indices that come up constantly in conversation (meme stocks, recent IPOs, crypto-mining and crypto-treasury companies) — each with its own live-fetched market cap rather than an index-derived one, since there's no index to derive them from. Small-cap coverage more broadly (S&P 600 and below, as a full tier) is deliberately not included yet: the small-cap index funds I tried publish holdings that don't fully replicate their index — one showed a company with a real multi-billion-dollar market cap holding a position of literally a few thousand dollars, which would have produced nonsense debt/cash ratios if used to derive market cap. Rather than publish numbers built on data I don't trust, that tier is left out until there's a reliable source for it.
Ticker screener data sources. Long-term debt, cash & equivalents, and business classification all come directly from each company's own SEC filings (data.sec.gov), not a third-party aggregator — for every company, every plausible XBRL debt tag a filer might use is checked, and the single most recent full-year (10-K) value across all of them is taken — and where two tags report the same most-recent period (a company reporting both a narrow debt sub-category and a broader consolidated figure for the same date, which is common), the larger of the two is used, not whichever tag happened to be checked first. Both of these exist specifically because they were real bugs caught while building this: a naive "first tag with any data" lookup silently returned a years-stale $0 for one company whose reporting had moved to a different tag, and a same-date tie-break by list order alone understated another company's real ~$16B debt load by a factor of 700 because a minor note class happened to share a reporting date with the true consolidated total. Cash uses the opposite tie-break, deliberately: the plain, unrestricted cash tag is preferred over a broader-sounding "cash and restricted cash" tag even when both exist for the same date, because for exchange and clearinghouse operators specifically, that broader tag can include customer-segregated margin collateral the company is legally required to hold but that isn't its own money — one clearinghouse's own filings showed $4.4B of actual cash and $164B of customer collateral bundled under the combined tag, which would have made its cash ratio meaningless if used. The debt tag list itself was also audited directly rather than assumed complete: several REITs and homebuilders (Realty Income, Digital Realty, Boston Properties, Extra Space Storage, Essex Property Trust, D.R. Horton, Mid-America Apartment, PulteGroup) report their real debt under tags like NotesPayable, SeniorNotes, or UnsecuredDebt rather than the more generic LongTermDebt tags this started with, and without those added, extraction was silently falling back to years-stale figures — Realty Income's had resolved to $4.0B from a 2016 filing instead of the real $25.0B on its 2025 balance sheet. One tag that looked like it belonged on that list, "finance lease liability," was tested and deliberately left out: it's a separate, narrower liability category, not an alternative total, and treating it as one wrongly let it outcompete real bond debt on a couple of names before that was caught and reverted. Activity classification starts from each filer's SEC-assigned SIC industry code, with a longer list of named, reasoned overrides for cases where the SIC code alone would mislead — BlackRock is coded under a legacy broker-dealer SIC despite being a fee-based asset manager with no lending or insurance operations; Visa and Mastercard are payment networks, not the entities issuing credit or earning interest (partner banks do that); companies like Boeing, Honeywell, and TransDigm are marked "questionable" rather than pass or fail because their commercial and defense revenue isn't cleanly separable in public filings. Those overrides are visible in the tool's own verdict text for the names they apply to, not hidden.
Market capitalization. For the roughly 130 largest constituents, market cap is pulled live, per-company, from Massive Market Data. For the remaining constituents, live per-company lookups weren't practical at this scale within the API's rate limits, so market cap is derived: each company's index weight (from the SPY or MDY holdings file, matching which index it belongs to) is multiplied by a total index market value, calibrated separately for each fund against a handful of constituents where both the real market cap and the index weight are independently known. This is a standard technique, not a guess, but it has a known bias worth stating plainly: index weights are float-adjusted (they exclude insider- and founder-held shares), so companies with concentrated ownership — families, founders, or governments holding a large stake — will show a derived market cap somewhat below their true figure. Practically, that pushes debt and cash ratios for those specific names slightly higher than reality, which biases toward flagging them fail or questionable rather than incorrectly passing them — the safer direction for a screen like this to be wrong in, but a real limitation, not a hidden one. It's also the reason the mid-cap calibration was checked before use, not assumed to work the same way as the large-cap one: the mid-cap fund's calibration points clustered within about 11% of each other (tight, trustworthy), while a separate small-cap fund tested for a broader expansion produced calibration points that disagreed by orders of magnitude for its smallest holdings — the signal that its holdings data wasn't reliable enough to use, described above. Each entry in the tool's underlying data is tagged with whether its market cap is live or derived. As before, the debt figure used is long-term debt only (not short-term or total liabilities), making every debt ratio here conservative rather than overstated. A small number of names don't cleanly report a long-term debt figure under any standard SEC tag and are marked "questionable" for that reason rather than assigned a guessed number.
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.
