Are Stocks Halal? Shariah Screening Explained for South African Muslims

Can a Muslim invest in stocks? The short answer is yes — but not all stocks. Islam permits investing in companies and sharing in their profits, because this represents genuine economic participation and ownership in a real business. What it prohibits is investing in companies whose business is itself impermissible, or companies that are structurally reliant on riba. This guide explains exactly how to determine whether a stock is halal.

Why Stock Ownership Is Permissible in Islam

When you buy a share, you become a part-owner of a company. Your return comes from the company’s profits — a permissible form of income in Islam, analogous to being a business partner. This is fundamentally different from lending money at interest. The profit motive, risk-sharing, and real economic activity at the heart of equity investing are entirely consistent with Islamic finance principles.

The question is not “are stocks halal?” The question is “is this specific stock halal?”

The Two-Level Shariah Screening Process

Level 1: Business Activity Screen

A company’s primary business — where most of its revenue comes from — must be permissible. Companies are excluded from Shariah-compliant investment if their core business is:

• Conventional banking, insurance, or financial services (the business model is riba-based)
• Alcohol production, distribution, or retail
• Tobacco
• Pork products
• Gambling and gaming
• Adult entertainment
• Weapons manufacturing (particularly weapons used against civilians)

A company that derives a small percentage of revenue from an impermissible activity (typically less than 5%) may still pass if the primary business is permissible — though this threshold varies by Shariah standard. The impermissible income portion must then be purified through charity donation.

Level 2: Financial Ratio Screen

Even companies with a permissible primary business can fail Shariah screening if their financial structure is too reliant on riba. Three key ratios are tested. Thresholds vary between Shariah standard-setting bodies (AAOIFI, Dow Jones Islamic Market, MSCI Islamic), but common benchmarks are:

• Interest-bearing debt — total interest-bearing debt below 33% of total assets (or market capitalisation, depending on the standard)
• Interest income — interest income plus impermissible income below 5% of total revenue
• Cash and receivables — cash and interest-bearing deposits below 33% of total assets; accounts receivable below 49% of total assets

Income Purification

Even in a well-screened portfolio, some small portion of income may be tainted by impermissible activities — for example, a permissible company that earns a small amount of bank interest on its cash holdings. Shariah standards require “income purification”: donating the impermissible income percentage to charity. A Shariah-compliant financial advisor calculates this annually. It is typically a small amount — but it is an obligation.

Where to Find Shariah-Screened Stocks in South Africa

• JSE Shariah-compliant securities list — the JSE publishes a list of Shariah-compliant listed securities, reviewed periodically by a Shariah supervisory board
• FTSE/JSE Islamic indices — tracks Shariah-screened JSE-listed shares
• MSCI Islamic Index and S&P 500 Shariah Index — for global stocks, accessible to South African investors through offshore investment platforms. Read our guide on Shariah-compliant offshore investing
• Shariah-compliant ETFs — the most practical option for most investors, as the screening is done by the fund’s Shariah supervisory board. Read our guide on are ETFs halal

Common Questions: South African Stocks

Are South African banks halal to invest in? No. Standard Bank, FirstRand, Absa, Nedbank, and Capitec all fail the business activity screen because their primary business is conventional banking — a riba-based model.

Are resource stocks (miners, oil) halal? Mining and resources companies typically pass the business activity screen because extraction and processing of physical commodities is permissible. They still need to pass the financial ratio screen.

Are technology companies halal? Many technology companies pass both screens. Their primary business (software, hardware, services) is permissible, and many carry relatively little interest-bearing debt. This is why major global Shariah equity indices include significant technology exposure — always check the current index composition.

Screening Is Not a One-Time Exercise

A stock that passes Shariah screening today may fail in the future — if the company’s business changes, its debt levels increase, or its financial ratios shift. Shariah-compliant indices are reviewed periodically (typically quarterly or semi-annually). If you are managing your own stock portfolio, you need to screen regularly — not just at the point of purchase. Most South African Muslim investors find it more practical to use Shariah-certified ETFs or unit trusts, where ongoing screening is managed by the fund provider.

Build a Halal Equity Portfolio

Shariah-compliant equity investment is one of the most important wealth-building tools for South African Muslims. The key is applying the screening correctly, purifying income annually, and integrating your equity holdings into a broader halal portfolio.
