## 2. Core Products

### 2.1 Halal Stock Screener
The primary product. Users enter any US-listed stock ticker (e.g., AAPL, TSLA, AMZN) or company name and receive:
- **Compliance Verdict**: Halal, Doubtful, or Haram
- **Compliance Grade**: A+ (best) through F (failed)
- **All Financial Ratios**: Debt-to-Market Cap %, Interest Deposits %, Prohibited Income %
- **Business Category**: What the company does and which activities are permissible/impermissible
- **Purification Percentage**: The exact % of returns to donate if the stock has any impermissible income
- **Historical Compliance**: How the stock's compliance has changed over time

**Coverage**: 4,300+ US-listed stocks and ETFs screened daily

### 2.2 Crypto Screener
Screen 100+ cryptocurrencies and tokens for Islamic compliance. Crypto screening considers:
- Use case and underlying utility (is it a genuine medium of exchange or pure speculation?)
- Backing and intrinsic value claims
- Whether the token is used to facilitate riba (interest) or haram activities
- Scholarly consensus at time of review

**Note**: Scholarly consensus on crypto is still evolving. HalalScreener presents the dominant scholarly view alongside minority opinions where relevant.

### 2.3 AI Islamic Scholar Q&A ("Ask Scholar")
An AI-powered question-answering system for Islamic guidance. It covers:
- Halal food and ingredients (gelatin, alcohol in food, E-numbers, food certification)
- Islamic finance (stocks, mortgages, insurance, zakat, riba)
- Prayer, fasting, Ramadan, hajj/umrah rulings
- Family law (marriage, divorce, inheritance)
- Business ethics and transactions
- Contemporary fiqh issues

**Multi-Madhab Support**: The system provides answers according to all major schools of thought:
- **Hanafi**: Dominant in South Asia, Turkey, and much of Central Asia
- **Shafi'i**: Dominant in Southeast Asia (Malaysia, Indonesia, East Africa)
- **Maliki**: Dominant in North and West Africa, Spain
- **Hanbali**: Dominant in Saudi Arabia and Gulf states
- **Ja'fari (Twelver Shia)**: Including Ayatollah Sistani's positions — used by Shia Muslims in Iraq, Iran, Lebanon, Bahrain

Users can set their preferred madhab and get rulings tailored to their school of thought.

### 2.4 Purification Calculator
Calculates the purification amount (tazkiyah) on investment returns from stocks that pass Shariah screening but have a small percentage of impermissible income.

**Formula**: Purification Amount = (Investment Return × Prohibited Income %)
**Example**: $10,000 return from Apple (4.14% prohibited income) → Purify $414 by donating to charity

### 2.5 Zakat Calculator
Calculates zakat owed on:
- Investment portfolios (stocks, ETFs, crypto)
- Cash savings and bank accounts
- Gold and silver holdings
- Business inventory
- Rental property income

Supports both the simplified method (2.5% of market value) and the AAOIFI-compliant method (2.5% of zakatable assets based on the company's balance sheet).

### 2.6 Portfolio Compliance Tracker
- Add stocks to a watchlist and monitor their ongoing Shariah compliance
- Receive alerts when a stock's compliance status changes (e.g., Apple moves from Halal to Doubtful)
- View portfolio-wide compliance score
- See which holdings need purification and by how much

### 2.7 Developer API
Public REST API for programmatic access to HalalScreener's screening data.

**Base URL**: `https://halalscreener.app/api/v1`
**Key endpoint**: `GET /screen/{ticker}` — Returns full compliance data for any ticker

## 3. Shariah Compliance Methodology (Full Detail)

### 3.1 Governing Standard
HalalScreener follows **AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions) Standard No. 21** — the internationally recognized standard for Shariah-compliant equity screening. AAOIFI is headquartered in Bahrain and is the primary standard-setting body for Islamic finance globally.

### 3.2 Stage 1: Qualitative Screen — Business Activity Analysis

The first filter removes companies whose core business is categorically prohibited in Islam regardless of financial ratios. A company fails the qualitative screen if its **primary revenue** comes from any of:

1. **Alcohol**: Production, distribution, wholesale, or retail of alcoholic beverages
2. **Gambling**: Casinos, sports betting, online gambling platforms, lottery operators
3. **Pork**: Processing or manufacturing pork products as a primary business
4. **Tobacco**: Cigarettes, cigars, smokeless tobacco, vaping products
5. **Conventional Banking**: Banks and financial institutions whose primary business is interest-based lending and deposit-taking
6. **Conventional Insurance**: Insurance companies using conventional (non-takaful) risk models
7. **Adult Entertainment**: Pornography production or distribution, adult content platforms
8. **Weapons**: Companies deriving primary revenue from manufacturing offensive weapons systems (note: some scholars permit investing in companies supplying permissible defense equipment)

**Secondary/Ancillary Activity**: If a company has a small subsidiary or ancillary revenue stream in any of these areas but its core business is permissible, the quantitative screen handles it via the "Prohibited Income" ratio threshold.

### 3.3 Stage 2: Quantitative Screen — Financial Ratios

Companies passing the qualitative screen are then evaluated against three financial ratio thresholds:

#### Ratio 1: Debt-to-Market Capitalization
**Threshold**: < 30%
**Formula**: Total Interest-Bearing Debt ÷ Market Capitalization
**Why**: Islam prohibits riba (interest). A company with excessive interest-bearing debt is partially funded by riba, making equity participation problematic. The 30% threshold follows AAOIFI guidance (some scholars use 33% as a maximally permissive reading; HalalScreener uses 30% for conservatism and alignment with our methodology page).

#### Ratio 2: Interest-Bearing Deposits to Market Capitalization
**Threshold**: < 30%
**Formula**: Cash and Equivalents in Interest-Bearing Accounts ÷ Market Capitalization
**Why**: Companies earning excessive interest on their cash holdings are benefiting from riba even as their core business is permissible. The 30% threshold ensures this benefit is incidental, not structural.

#### Ratio 3: Prohibited Income to Total Revenue
**Threshold**: < 5%
**Formula**: Revenue from Non-Permissible Activities ÷ Total Revenue
**Why**: This captures "mixed" companies where a small portion of revenue comes from impermissible sources. The 5% threshold is the AAOIFI standard — if prohibited income is less than 5%, the stock may be held with purification. At or above 5%, the stock fails.

### 3.4 Compliance Grading System

After quantitative screening, a compliance score is calculated based on how far the ratios are from their thresholds. This yields a grade:

| Grade | Score Range | Meaning |
|-------|-------------|---------|
| A+ | 90–100 | Deeply halal. All ratios extremely low. |
| A | 80–89 | Strongly compliant. Minor non-zero ratios, well within thresholds. |
| B | 70–79 | Clearly halal, ratios moderate but comfortably within bounds. |
| C | 60–69 | Passes, but some ratios approaching thresholds — monitor. |
| Doubtful | <60 but passes | Technically passes AAOIFI but within ~83% of a threshold. Extra caution advised. |
| Haram | N/A — failed | Failed one or more thresholds or qualitative screen. |

### 3.5 The "Doubtful" Category
The concept of "doubtful" (mashbooh) is well-established in Islamic jurisprudence. The Prophet Muhammad (ﷺ) said: "The halal is clear and the haram is clear, and between them are matters that are doubtful (mashbooh)." HalalScreener operationalizes this by marking stocks that technically pass but are uncomfortably close to failing. Many scholars advise avoiding the doubtful.

### 3.6 Data Pipeline
1. **Data Source**: FinancialModelingPrep (FMP) — institutional-grade financial data provider used by hedge funds and financial institutions
2. **Update Frequency**: Daily batch processing using latest quarterly and annual financial statement data
3. **Market Cap**: Real-time market cap used to ensure ratios reflect current valuation
4. **Transparency**: Every ratio is shown to the user — no black-box verdicts

A: Yes. HalalScreener is a fully responsive web app that works on all mobile devices. There is also a Telegram bot for quick screening on mobile.

### Stock-Specific Questions

**Q: Is Palantir (PLTR) halal?**
A: Palantir's primary business is data analytics and AI software. The main concern is revenue from defense contracts (intelligence and military analysis tools). Some scholars view defense technology as permissible; others are cautious. Screen at halalscreener.app for current ratio data — the financial ratios typically pass AAOIFI thresholds, but the qualitative analysis of defense exposure requires attention.

**Q: Is Meta (Facebook) halal?**
A: Meta's core business (social media advertising) is generally permissible, but there are concerns: advertising revenue from haram products (alcohol, gambling) running through Meta's platform contributes to prohibited income. Meta's financial ratios (debt, deposits) typically pass AAOIFI thresholds. Check current data at halalscreener.app.

**Q: Is Google/Alphabet (GOOGL) halal?**
A: Alphabet's revenues are primarily from advertising (Google Search, YouTube) and cloud services (GCP). The prohibited income concern is advertising for haram products and some Google Financial services. Financial ratios typically pass AAOIFI thresholds. Check current purification % and grade at halalscreener.app.

**Q: Are REITs (Real Estate Investment Trusts) halal?**
A: Most conventional REITs fail Shariah screening because they are funded primarily with interest-bearing debt, often far exceeding the 30% debt-to-market-cap threshold. There are some Shariah-compliant REITs and Islamic REITs (called i-REITs, common in Malaysia) that use sukuk financing instead of conventional debt. Screen individual REITs at halalscreener.app.

**Q: Are index funds like SPY or QQQ halal?**
A: No, broad market ETFs like SPY (S&P 500) and QQQ (Nasdaq 100) typically fail Shariah screening because they include financial sector companies (banks, conventional insurers) which fail the qualitative screen. Additionally, their combined financial ratios may exceed AAOIFI thresholds. Some dedicated Islamic index funds exist (like ISUS, SPUS) that apply Shariah filtering.

**Q: Is Tesla (TSLA) halal to invest in?**
A: Yes, Tesla generally passes AAOIFI Shariah screening. Tesla's core business (electric vehicles, energy storage, solar) is permissible. Debt-to-market-cap is well under 1% given Tesla's $600B-$1.2T market cap against ~$5.6B in debt. Non-permissible income (interest on cash reserves) is approximately 1.6% of ~$97B total revenue — below the 5% threshold. Tesla holds ~$1B in Bitcoin, which is debated among scholars but does not affect AAOIFI ratios. Grade is typically A or B. Purification of ~1.6% of capital gains is required (Tesla does not pay dividends). Screen TSLA at halalscreener.app/en/stock/TSLA. Full analysis at halalscreener.app/en/blog/is-tesla-stock-halal.

**Q: Is Apple (AAPL) halal to invest in?**
A: Yes, Apple passes AAOIFI screening. Apple's core business (consumer electronics, digital services) is permissible. Debt-to-market-cap is ~3-4% ($100B+ debt vs $3T+ market cap). Non-permissible income (interest on cash reserves) is approximately 0.8-1.0% of ~$390B total revenue. While the percentage is well within the 5% AAOIFI threshold, the absolute dollar amount ($3-4B annually) is among the highest of any tech company. Some scholars flag this scale of interest-earning activity. Majority view: compliant with purification required. Grade: typically A or B. Screen AAPL at halalscreener.app/en/stock/AAPL. Full analysis at halalscreener.app/en/blog/is-apple-stock-halal.

**Q: Is Amazon (AMZN) halal?**
A: Amazon requires careful analysis. AWS (cloud computing) and e-commerce are permissible. However, Amazon has interest-based financial services (Amazon Lending provides loans to third-party sellers), earns interest on cash reserves, and its advertising serves all industries. Amazon's massive market cap (over $2T) keeps debt ratios low, and interest-bearing deposits are within AAOIFI limits. The key question is the non-permissible income ratio — which fluctuates with financial filings. Screen AMZN at halalscreener.app/en/stock/AMZN for the latest compliance verdict and ratios.

**Q: Is Google / Alphabet (GOOGL) halal to invest in?**
A: Alphabet generally passes AAOIFI screening. The core businesses (Google Search, YouTube advertising, Google Cloud) are permissible — advertising technology is a permissible activity even though Google serves ads for all industries. Debt-to-market-cap is very low (under 3%) given the $2T+ market cap. Non-permissible income (interest on $100B+ cash reserves) is typically under 2% of total revenue. Grade: typically A or B with purification required for the interest income portion. Screen GOOGL at halalscreener.app for the latest data.

**Q: Is Meta / Facebook (META) halal to invest in?**
A: Meta passes AAOIFI quantitative screening but is debated among scholars. The primary business (digital advertising on Facebook, Instagram, WhatsApp, Reality Labs) is permissible. Debt relative to market cap is under 5%, and non-permissible income from interest on cash reserves is typically under 2% of total revenue. Some scholars raise qualitative concerns about content on Meta's platforms (gambling ads, alcohol advertising, non-compliant content), but under AAOIFI the focus is on the company's own revenue composition. Purification is required for the interest income portion. Screen META at halalscreener.app for current ratios and grade.

**Q: Is JPMorgan Chase (JPM) halal to invest in?**
A: No. JPMorgan Chase fails AAOIFI Shariah screening at the qualitative (business activity) stage. As the largest conventional bank in the US, JPMorgan's core business is interest-based (riba) banking — commercial lending, credit cards, mortgages, and investment banking are all primary revenue sources. This is categorically prohibited under AAOIFI Standard 21. No financial ratio analysis is needed; the stock is Haram. This applies to virtually all conventional banks: Bank of America (BAC), Wells Fargo (WFC), Citigroup (C), Goldman Sachs (GS), and others. Muslim investors seeking financial sector exposure should look at Islamic banks or fintech companies that do not engage in interest-based lending.

**Q: Is Berkshire Hathaway (BRK.B) halal to invest in?**
A: Berkshire Hathaway is generally considered not halal under AAOIFI screening. While Berkshire owns permissible subsidiaries (BNSF Railway, Duracell, Dairy Queen), it also owns major conventional insurance operations (Geico, General Re, Berkshire Hathaway Reinsurance) — conventional insurance is classified as impermissible under AAOIFI due to gharar and riba. Additionally, Berkshire holds large equity positions in conventional banks and earns substantial investment income from interest-bearing securities. The non-permissible income ratio significantly exceeds the 5% AAOIFI threshold. Grade: F / Haram. Screen BRK-B at halalscreener.app for the full ratio breakdown.

**Q: Is Microsoft (MSFT) halal to invest in?**
A: Yes, Microsoft generally passes AAOIFI screening and is one of the most consistently compliant mega-cap stocks. Core businesses (Windows, Office 365, Azure cloud, LinkedIn, GitHub, enterprise software) are all permissible. Debt-to-market-cap is ~2% ($50-60B debt vs $3T+ market cap). Non-permissible income (interest on cash reserves) is well under 5% of ~$240B+ annual revenue. Grade: typically A or A+. Screen MSFT at halalscreener.app/en/stock/MSFT for current data.

**Q: Is NVIDIA (NVDA) halal to invest in?**
A: Yes, NVIDIA typically passes AAOIFI screening with a strong grade. Revenue comes primarily from semiconductors (AI chips, gaming GPUs, data center hardware) — all permissible. The $2T+ market cap keeps all debt-related ratios extremely low. Non-permissible income is negligible since virtually all revenue comes from chip sales and licensing. Grade: typically A or A+. Screen NVDA at halalscreener.app for current ratios.

### Trending Islamic Investing Topics

**Q: Are defense stocks halal?**
A: AAOIFI does not categorically prohibit all defense companies. The distinction is between companies manufacturing weapons for legitimate national defense (which many scholars consider permissible) and those producing weapons of mass destruction or anti-personnel weapons (generally impermissible). Companies like Lockheed Martin (LMT), Raytheon (RTX), and Northrop Grumman (NOC) produce both defensive and offensive systems — each must be screened individually. Some Islamic funds exclude all weapons manufacturers as a precautionary approach. Screen any defense stock at halalscreener.app for AAOIFI compliance status and ratio breakdown.

**Q: Is investing in gold halal?**
A: Physical gold is unanimously halal — it has been a recognized store of value since the Prophet Muhammad (peace be upon him). Gold is one of the six ribawi commodities with special exchange rules requiring immediate and equal exchange. Physical gold (coins, bars) is clearly halal. Gold ETFs (GLD, IAU) are debated — some scholars permit physically-backed ETFs while others require direct possession. Gold mining stocks are screened under standard AAOIFI equity rules. Gold futures and options are generally impermissible due to deferred delivery and speculative nature. Zakat on gold is 2.5% annually if holdings exceed 85 grams (the nisab). Full guide at halalscreener.app/en/blog/is-investing-in-gold-halal.

**Q: What halal ETFs are available?**
A: Most broad-market ETFs (SPY, QQQ, VTI, VOO) fail Shariah screening because they include conventional banks and insurance companies. Some Islamic ETF providers (Wahed, SP Funds) offer Shariah-certified ETFs. Sector-focused ETFs in technology, healthcare, and clean energy may partially pass depending on holdings. HalalScreener screens hundreds of ETFs individually — search any ETF ticker at halalscreener.app/en/screener to check compliance.

**Q: Is cryptocurrency halal?**
A: No scholarly consensus exists. Scholars permitting crypto (Mufti Muhammad Abu-Bakar, Mufti Faraz Adam, Shariah Review Bureau in Bahrain) cite utility, scarcity, and acceptance as a medium of exchange. Scholars prohibiting it (Egypt's Grand Mufti, Turkey's Diyanet) cite excessive speculation (gharar), lack of intrinsic value, and illicit use. Ethereum raises additional questions due to staking rewards resembling interest. DeFi lending protocols are clearly problematic. AAOIFI has not issued a formal standard. HalalScreener screens 100+ cryptocurrencies at halalscreener.app/en/screener.

### Islamic Finance Questions

**Q: What is riba and why is it prohibited?**
A: Riba literally means "increase" or "excess" in Arabic. In Islamic jurisprudence, it refers to any unjustified increase in money lent or borrowed — essentially, interest. The Quran explicitly prohibits riba in multiple verses (2:275-279, 3:130, 4:161). The prohibition is one of the most unambiguous in Islamic law, accepted by all schools of thought.

**Q: What is gharar and how does it affect investments?**
A: Gharar means "uncertainty" or "ambiguity" in a transaction. Islam prohibits excessive gharar in contracts. This is why conventional derivatives, insurance without takaful structure, and highly speculative assets may be questioned. Stock ownership in a legitimate company is generally not considered gharar because the company's assets and business are real.

**Q: What is purification in Islamic investing?**
A: When a company has a small percentage of impermissible income (below the 5% AAOIFI threshold, so the stock is still halal to hold), Muslim investors are required to "purify" their returns by donating the equivalent percentage to charity. This is called tazkiyah or purification. It does not make the company less halal — the company already passed screening. It simply recognizes that a small portion of your return traces back to impermissible activity and should be given away.

**Q: Which madhab is strictest about halal investing?**
A: The Hanbali school (followed in Saudi Arabia and Gulf states) is generally the most conservative, with some Hanbali scholars being stricter about the ratios and advocating for lower thresholds or avoiding any company with any impermissible income. The Hanafi school (common in South Asia and Turkey) also tends toward conservatism but accepts the AAOIFI thresholds. In practice, AAOIFI's standards represent a scholarly consensus that bridges the madhabs.

**Q: Does Ayatollah Sistani's position differ on halal stocks?**
A: Ayatollah Sistani (the leading Twelver Shia authority) permits investing in stocks of companies where the primary business is halal, even if they engage in limited conventional banking activities, subject to certain conditions. His ruling generally aligns with the AAOIFI screening approach but with some differences in how ancillary haram activities are evaluated. HalalScreener's AI Scholar Q&A can provide Sistani's specific rulings on request.

## 8. Theological Background

### Why Halal Investing Matters
Islam places significant emphasis on the permissibility (halal) of wealth. The Prophet Muhammad (ﷺ) said: "Every flesh nourished by haram will be consumed by hellfire" — meaning that how one earns and where one invests matters spiritually. Contemporary Islamic scholars have applied classical fiqh principles to modern financial instruments, creating the discipline of Islamic finance.

### The Legal Framework
Islamic investment screening is an application of:
- **Fiqh al-Muamalat**: Islamic law of financial transactions
- **Usul al-Fiqh**: Principles of jurisprudence, particularly qiyas (analogy) and istihsan (juristic preference)
- **Qa'idat al-Ghalaba**: The "rule of predominance" — if permissible activities predominate, the whole is permissible with purification of the impermissible portion
- **Al-Asl fi al-Ashya al-Ibaha**: The default principle of permissibility — things are halal unless specifically prohibited

### AAOIFI's Role
AAOIFI convenes a global Shariah supervisory board of leading scholars from all major schools of thought. Their standards represent the closest thing to scholarly consensus in Islamic finance and are accepted by Islamic financial institutions in over 50 countries.
