What is Shariah Screening?
Shariah screening is the process of evaluating whether a publicly traded company meets Islamic principles for permissible investment. Scholars use a two-step methodology: qualitative screening (business activities) and quantitative screening (financial ratios).
Two-Step Screening Process
Step 1: Business Activity Screening
Check what the company does. Core business must be halal. Companies dealing in alcohol, gambling, pork, weapons, pornography, conventional finance, etc. are excluded.
Step 2: Financial Ratio Screening
Check financial health. Companies with excessive debt, interest income, or impure revenue are excluded or flagged for purification.
Why Screening is Necessary
Islam prohibits investing in businesses involved in haram (forbidden) activities and excessive interest-based dealings. Most modern companies have some involvement with conventional banks (loans, deposits), making pure screening impossible. Scholars developed tolerance thresholds based on necessity and modern economic reality.
Key Principle: Majority Rule
If a company's main business is halal but has minor impure income (like interest on cash deposits), it may still be permissible if: (1) impure income is below threshold (usually 5%), and (2) you purify your share of impure income through charity.
Business Activity Screening (Qualitative)
The first filter examines what the company actually does. Companies whose core business involves prohibited activities are automatically excluded.
Prohibited Business Activities
Financial Services
- Conventional banking
- Insurance (non-Takaful)
- Interest-based lending
- Derivatives trading
Food & Beverage
- Pork products
- Alcohol production/distribution
- Non-halal meat processing
- Bars & nightclubs
Entertainment
- Gambling & casinos
- Pornography
- Conventional music production
- Adult entertainment
Other
- Weapons & defense (debated)
- Tobacco (most scholars)
- Cloning & unethical biotech
- Hotels with bars (debated)

Technology
- • Software
- • Cloud services
- • E-commerce
- • SaaS platforms
Healthcare
- • Pharmaceuticals
- • Medical devices
- • Hospitals
- • Biotechnology
Retail
- • Clothing

Mixed Revenue (Debated)
What if company has 5% haram revenue?
Many companies have small haram revenue streams. For example:
- • Amazon: Sells alcohol & prohibited items (~1-2% of revenue)
- • Apple: Interest income on cash reserves (~0.5%)
- • Costco: Alcohol sales (~5%)
Scholarly opinion:If haram revenue is <5% and not the core business, stock may be permissible with dividend/gain purification. If >5%, most exclude it.
Financial Ratio Screening (Quantitative)
After passing business activity screening, companies must meet financial health thresholds to avoid excessive debt and interest-based dealings.
Standard Financial Ratios
Two major screening methodologies exist: AAOIFI (more strict, Middle East) and S&P/MSCI (more lenient, global indexes). Most platforms use variations of these.
AAOIFI Standards (Stricter)
Accounting and Auditing Organization for Islamic Financial Institutions
Total Debt / Market Cap
≤ 30%
Company's total debt should not exceed 30% of its market capitalization
(Cash + Interest-Bearing Securities) / Market Cap
≤ 30%
Liquid interest-bearing assets should be below 30% of market cap
Interest Income / Total Revenue
≤ 5%
Revenue from interest and other impermissible sources must be under 5%
Accounts Receivable / Total Assets
≤ 45%
To ensure company is not essentially a lender
S&P/MSCI Standards (More Lenient)
Used by S&P Dow Jones Islamic Indices and MSCI Islamic Indexes
Total Debt / 36-Month Avg Market Cap
≤ 33.33%
Debt must be under one-third of trailing 36-month average market cap
(Cash + Interest-Bearing Securities) / 36-Month Avg Market Cap
≤ 33.33%
Cash and interest-bearing instruments below 33.33%
Accounts Receivable / 36-Month Avg Market Cap
≤ 33.33%
Receivables should not exceed 33.33% of average market cap
Impermissible Income / Total Revenue
≤ 5%
Non-permissible income (interest, etc.) must be under 5%
Key Differences: AAOIFI vs S&P
| Criterion | AAOIFI | S&P/MSCI |
|---|---|---|
| Debt threshold | 30% | 33.33% |
| Comparison base | Current market cap | 36-month avg |
| Receivables check | ✓ (45% of assets) | ✓ (33% of mcap) |
| Impure income | ≤5% | ≤5% |
| Strictness | More strict | More lenient |
Real-World Examples
Pass: Microsoft (MSFT)
Shariah Compliant ✓
Passes both AAOIFI and S&P screening
Business: Software, cloud services (Azure), enterprise SaaS
✓ Core business is halal
Financial Ratios (approximate):
• Debt/Market Cap: ~15% ✓ Pass (under 30%)
• Cash/Market Cap: ~12% ✓ Pass (under 30%)
• Interest Income: ~0.8% ✓ Pass (under 5%)
Result: Halal with minor purification (0.8%)
Pass with Caution: Apple (AAPL)
Borderline / Debated
Some scholars permit, others exclude
Business: Electronics, smartphones, services (App Store, iCloud)
✓ Core business is halal
Financial Ratios (approximate):
• Debt/Market Cap: ~5% ✓ Pass
• Cash/Market Cap: ~8% ✓ Pass
• Interest Income: ~1.5% ✓ Pass (under 5%)
Concern:
• App Store sells music, gambling apps, prohibited content
• Haram revenue ~2-3% (debated)
Result: Some permit with purification, others exclude
Fail: JPMorgan Chase (JPM)
Not Shariah Compliant ✗
Fails business activity screening
Business: Conventional banking, interest-based lending, credit cards
✗ Core business is interest-based banking (haram)
Ratios dont matter:
When core business is prohibited, financial ratios are irrelevant.
Result: Not permissible under any standard
Fail: Diageo (DGE.L)
Not Shariah Compliant ✗
Alcohol producer
Business: Worlds largest spirits company (Johnnie Walker, Guinness, Smirnoff)
✗ Core business is alcohol production (haram)
Result: Strictly prohibited
Dividend Purification
If a Shariah-compliant company has minor impure income (under 5%), you should purify your portion of that income by donating it to charity.
How Purification Works
Example: Microsoft
Interest income: 0.8% of revenue
You receive dividend: £100
Purification needed: £100 × 0.8% = £0.80
Donate £0.80 to charity
Halal dividend after purification: £99.20

Capital Gains Purification?
Scholarly difference: Some scholars say purification only applies to dividends (company income). Others say it applies to capital gains too (since you owned part of impure income). Majority opinion: only dividends need purification. Consult your trusted scholar.
How to Verify Halal Status
Before buying a stock, verify its Shariah compliance through one of these methods:
Use Halal Stock Screeners
Free apps like Zoya, Islamicly, or our website provide real-time screening
Accuracy: High
Check Islamic Index Constituents
If stock is in S&P 500 Shariah, MSCI Islamic, FTSE Shariah, its pre-screened
Accuracy: Very High
Manual Screening
Read annual reports, calculate ratios yourself using AAOIFI/S&P standards
Accuracy: Varies
Ask a Scholar
Consult with a scholar knowledgeable in Islamic finance for specific cases
Accuracy: Very High
Our Screening on Zeenox
We use a combination of AAOIFI and S&P standards, plus business activity analysis. Our database is updated quarterly with latest financials.
Gray Areas & Scholarly Differences
Not all scholars agree on every aspect of stock screening. Here are common areas of difference:
Debt Ratio Thresholds
AAOIFI: 30% is maximum
S&P/MSCI: 33.33% is acceptable
Consensus: Most scholars accept either standard. Choose one methodology and stick to it.
Defense/Weapons Stocks
Prohibited: Weapons cause harm
Permissible: Defense is necessary for Muslim nations
Consensus: Depends on scholar. Many exclude weapons manufacturers but permit defense contractors.
Hotels with Bars/Restaurants
Prohibited: Facilitate alcohol consumption
Permissible: Alcohol is not main business (under 5%)
Consensus: Divided. Conservative: avoid. Lenient: permit if alcohol revenue under 5%.
Companies with Minor Haram Revenue
Exclude if any haram revenue
Permit if under 5% with purification
Consensus: Majority permit under 5% with purification. Minority say zero tolerance.
Music/Entertainment Companies
All music is haram, exclude
Instrumental music permissible, vocals debated
Consensus: Most scholars say music companies are not permissible. Debate ongoing.
What Should You Follow?
Choose a screening methodology (AAOIFI or S&P) and follow it consistently. If unsure about gray areas, consult a scholar you trust. Being cautious (avoiding doubtful stocks) is always safer. The Prophet ﷺ said: "Leave what causes doubt for what does not cause doubt."
Practical Tips
Always Verify Before Buying
Dont assume. Check screening status on Zoya/Islamicly or our website before buying any stock.
Screening Status Changes
A compliant stock can become non-compliant if ratios change. Review holdings quarterly.
Purify Dividends
Keep track of impure income percentages and purify your dividends/gains accordingly.
Use Islamic Indexes
S&P 500 Shariah, MSCI Islamic, FTSE Shariah indexes are professionally screened. Use as starting point.
When in Doubt, Avoid
If you're unsure whether a stock is halal, its safer to avoid it. Plenty of clearly halal options exist.
Document Your Research
Keep records of screening checks and purification calculations for your own reference.
