What Makes a Stock Halal?

When you look at buying shares of a company, Islamic scholars ask two practical questions: What does this company do? and How much debt and interest does it carry? These two screens work together to tell you whether owning a piece of that business aligns with Islamic principles.

Screen 1: What Does the Company Actually Do?

The first screen is simple: reject companies whose core business is inherently impermissible. This is about what they primarily earn their money from.

Companies to avoid:

• Alcohol and tobacco – brewing, distilling, tobacco manufacturing. This is the clearest case across all Islamic standards.
• Conventional banking and finance – banks that lend at interest, insurance companies that operate on conventional (interest-based) models. Islamic banks and Sharia-compliant insurance (takaful) are generally acceptable.
• Gambling – casinos, online betting platforms, lottery operators.
• Pork production and processing – pig farms, pork product manufacturers.
• Adult entertainment – companies whose primary business is adult content production or distribution.
• Conventional weapons manufacturing – companies primarily making weapons of war. (Defense companies that also make civilian products are often evaluated more carefully by scholars.)

Many global stock screens also exclude companies involved in non-core controversial activities, but the above are the main Sharia concerns. Some scholars are more conservative; others more lenient on borderline cases. This is why Ansaar's halal filter on the screener lets you see the business description – so you can make your own informed decision or consult a scholar if you're unsure.

The key principle: you're asking, Is my money supporting a business I believe in? If the answer is clearly no, that's your signal.

Screen 2: The Financial Ratio Screen

The second screen looks at the company's balance sheet and income statement. Even a company with a lawful business might carry so much debt or interest income that owning it becomes problematic. Islamic scholars developed financial thresholds to catch this.

The most widely used standard is AAOIFI (Accounting and Auditing Organisation for Islamic Financial Institutions), though other standards like the Dow Jones Islamic Market (DJIM) index have their own versions.

The main thresholds (AAOIFI-style):

• Interest-bearing debt: Should not exceed roughly 30–33% of the company's total assets (or market capitalisation, depending on the method). This limits how much the company's financing depends on forbidden loans.
• Interest income: Should be less than roughly 5% of total revenue. This stops companies that profit significantly from lending at interest.
• Other non-compliant income: Income from impermissible sources (e.g., a food company earning interest on its cash reserves) should also stay below roughly 5% of revenue.

A simplified example: Imagine a textile company with 100 crore in assets. If it has 40 crore in interest-bearing debt, it fails the debt screen (40 is above 33%). Or if its total revenue is 50 crore and it earns 3 crore in interest income, it fails the income screen (3 is above 5% of 50). In either case, Sharia scholars would say the shares are not suitable to hold without purification (we'll cover that later).

Why Two Screens?

The two screens catch different problems. Screen 1 stops you from funding a business you shouldn't be in (core harm). Screen 2 stops you from funding a business that is mostly fine but has hidden problematic debt or interest earnings (systemic haram creeping in). Together, they're the foundation of Sharia-compliant investing.

How Ansaar Helps

On the Ansaar screener, you can filter by our halal flag, which applies these two screens to Indian stocks. The filter shows you companies that pass both tests, so you don't have to manually check every balance sheet. You can also see the business description and, over time, the financial metrics that drive the decision.

This filter is a starting point – not a replacement for your own research or a scholar's guidance. But it saves you the legwork of reading 100 financial statements.

Key takeaways

• Screen 1: Reject companies whose core business is alcohol, gambling, conventional banking, pork, tobacco, adult entertainment, or weapons.
• Screen 2: Reject companies with interest-bearing debt above roughly 30–33% of assets, or interest income above roughly 5% of revenue.
• Different standards use slightly different thresholds – scholars differ.
• Use Ansaar's halal filter on the screener as a starting point, then do your own research.
