Halal Investing 101: A Beginner's Guide
6 min read · Last reviewed 3 June 2026
Halal investing means putting your money only into businesses and instruments that comply with Islamic law (Shariah). For Muslim investors it isn't a niche preference — it's an obligation: wealth should grow through permissible (halal) means and avoid the forbidden (haram).
The two things Shariah cares about
Scholars assess a listed company on two independent tests. A stock has to pass both to be considered compliant:
- Business activity — what the company actually does. Alcohol, tobacco, gambling, conventional (interest-based) banking and insurance, pork, adult content and weapons all fail outright.
- Financial ratios — how the company is financed. Even a permissible business fails if it carries too much interest-bearing debt or earns too much of its income from interest.
Why interest (riba) is the central issue
The prohibition of riba (interest) is the thread running through every financial screen. A company drowning in interest-bearing loans, or one that earns a large slice of its revenue from lending money, is participating in riba — so scholars cap how much of either is tolerable before a stock becomes non-compliant.
How Ethiqly helps
Ethiqly screens stocks against the AAOIFI standard automatically — pulling each company's filings, running the business and financial tests, and giving you a clear verdict instead of a spreadsheet. You can also screen the market for compliant names and calculate the zakat due on your holdings.
Three steps to start
- Check any stock you already own for its compliance verdict.
- Replace non-compliant holdings with screened alternatives over time.
- Track ongoing compliance — a stock can drift out of compliance as its debt or income mix changes, so screening is a habit, not a one-off.
Remember: screening tools are an aid, not a fatwa. Methodologies differ between scholars and schools of thought — for a ruling specific to your situation, consult a qualified scholar.
