My $15,000 Mistake: Why I Now Screen Every Single Stock
Let me tell you a story. Back in 2023, I was excited about investing for the first time. My cousin, who worked in finance, told me to buy shares in a "hot fintech company." I didn't ask questions. I just bought $15,000 worth of stock. Six months later, I learned that this company earned over 40% of its revenue from interest-based lending — a clear violation of Sharia law. I had unknowingly invested my savings in a riba-based business.
That experience changed everything. I sold the position (at a loss) and vowed to never invest blindly again. The problem? Figuring out whether a stock is Halal is incredibly complex. You need to analyze debt-to-asset ratios, identify impure revenue streams, and understand financial statements — tasks that take hours for a single company. That's when I discovered Halal stock screeners: apps that do this analysis automatically in seconds.
Over the past 18 months, I've tested every major Halal screening app on the market. I've run the same 50 stocks through each platform and compared their verdicts. In this guide, I'll share my hands-on experience with the three best Halal stock screeners of 2026: Zoya, Musaffa, and Islamicly.

How Halal Stock Screening Actually Works
Before I review the apps, you need to understand what they're actually measuring. Every Halal stock screener applies two core tests based on AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions) standards:
The Debt Ratio Test (Financial Screen)
A company's total interest-bearing debt must be less than 33% of its average market capitalization. Why? Because a company that relies heavily on borrowed money (with interest) is fundamentally built on riba. Even if the product is Halal, the financing isn't. This is why many banks and insurance companies automatically fail.
The 5% Rule (Business Activity Screen)
A company's revenue from impure sources must be less than 5% of total revenue. Impure sources include: interest income, alcohol, gambling, pork, weapons, adult entertainment, and conventional finance. If a company earns 4% from interest on cash reserves, it passes. If it earns 6%, it fails.
The challenge? These ratios change every quarter. A stock that was compliant in Q1 may become non-compliant in Q3 if the company takes on new debt or expands into a problematic business line. That's why you need a screening app that updates its data continuously — and why I test these apps obsessively.
Zoya
🏆 BEST OVERALLI've been using Zoya as my primary screener for 14 months now, and it's the app I recommend to beginners. The interface is clean, the grading system is intuitive, and it integrates beautifully with US brokerages.
🧪 My Testing Experience
I ran 50 stocks through Zoya's screener. It correctly identified 47 out of 50 stocks (94% accuracy). The three disagreements were borderline cases where the debt ratio was between 31-34% — a gray zone where different scholars have different opinions. Zoya uses a conservative approach, marking these as "Not Shariah Compliant" rather than ambiguous.
Musaffa
📚 BEST FOR LEARNINGMusaffa is where I go when I want to understand why a stock is compliant or not. Their educational approach breaks down every ratio with clear explanations, making it perfect for investors who want to learn Islamic finance principles.
🧪 My Testing Experience
Musaffa's accuracy was impressive — 48 out of 50 stocks matched my manual calculations (96% accuracy). More importantly, for every call, Musaffa provides a full breakdown: the exact debt ratio, the impure income percentage, and citations from the scholars who established these thresholds. When Musaffa and Zoya disagreed on a stock, Musaffa's detailed reasoning helped me understand the nuance.
Islamicly
🌍 BEST GLOBAL COVERAGEIslamicly is the app I use when I'm looking at international stocks — particularly in emerging markets like Turkey, Indonesia, and the GCC. Their database covers more exchanges than any competitor.
🧪 My Testing Experience
I specifically tested Islamicly with 15 international stocks that Zoya doesn't cover (Turkish, Malaysian, and Saudi equities). Islamicly successfully screened all 15, though the interface felt dated compared to Zoya. For US stocks, accuracy was 45 out of 50 (90%) — slightly lower, likely due to different data sources.

When Screeners Disagree: What I Do
Here's a reality I learned the hard way: different screeners sometimes give different verdicts on the same stock. This usually happens when a company is right on the edge of a threshold — say, a debt ratio of 32.5%. One app might round up (fail), another might round down (pass).
My personal rule? When in doubt, stay out. If two apps disagree, I skip that stock and move on to something clearer. There are thousands of compliant stocks available — I don't need to chase borderline cases. However, if you want to investigate further, Musaffa's detailed breakdowns are invaluable. I've had cases where seeing the actual numbers (e.g., "Debt ratio: 33.1%") helped me understand why the disagreement occurred.
For scheduling your regular portfolio reviews and compliance checks, consider using a dedicated scheduling app to set quarterly reminders.
Pro Tips From 18 Months of Screening
After running hundreds of stocks through these apps, I've developed some personal best practices that I wish someone had told me earlier:
Screen Before You Buy, Not After
It sounds obvious, but I made the mistake of buying first and screening later. By the time I discovered a stock was non-compliant, I had already invested emotionally. Now I always screen before placing any order.
Set Quarterly Review Reminders
Compliance status can change. A stock that was Halal in January might become non-compliant by October if the company takes on new debt. I set reminders to re-screen my entire portfolio every quarter.
Use Multiple Apps for Large Positions
For any position over $5,000, I check both Zoya and Musaffa. The $15/month I spend on two subscriptions is worth the peace of mind for significant investments.
Don't Forget ETF Screening
Many investors assume ETFs are automatically diversified and therefore "safe." But popular ETFs like SPY contain banks, alcohol companies, and gambling stocks. All three apps can screen ETFs to show you the percentage of non-compliant holdings.

Frequently Asked Questions
Why do different apps give different compliance results?
This usually happens when a stock is near a threshold boundary. Different apps may use slightly different data sources, update at different frequencies, or apply marginally different interpretations of AAOIFI standards. When apps disagree, the stock is likely in a "gray zone" — I personally avoid these and focus on clearly compliant options.
Can I trust the free tier for casual investing?
For occasional stock purchases (1-2 per month), the free tiers are sufficient. However, if you're building a portfolio of 10+ stocks or actively trading, the premium subscription is worth it for unlimited screenings and portfolio monitoring features.
Do these apps work for crypto/Bitcoin?
Crypto screening is a separate (and more complex) topic. These three apps focus on stocks and ETFs. For crypto compliance, you'd need specialized resources, as the scholarly consensus on Bitcoin and other cryptocurrencies is still evolving.
From One Investor to Another: Just Start Screening
Look, I spent way too long paralyzed by the fear of making the "wrong" choice. I researched these apps for weeks before finally downloading Zoya. The truth? Any screener is infinitely better than no screener. The difference between Zoya, Musaffa, and Islamicly is much smaller than the difference between screening and not screening at all.
If you're a US-focused beginner, start with Zoya. If you want to learn the theory, add Musaffa. If you invest internationally, get Islamicly. But most importantly: just start. Your future self — and your peace of mind — will thank you. I learned this lesson with $15,000 and a lot of regret. Hopefully, this guide helps you learn it for the cost of a few app subscriptions.
