Halal investing — history

Modern halal investing — equity investing constrained by Shariah — is younger than most people realize. The frameworks underpinning Khabir's screen are largely a product of the last 30 years, even though their underlying jurisprudence is centuries old. This page covers the history.

Pre-1990s: classical fiqh meets modern markets

Classical Islamic jurisprudence (fiqh) deals extensively with partnerships (musharakah), profit-sharing (mudarabah), and prohibitions on usury (riba). But the public listed-equity market — where you can own a fractional share of a corporation by pressing a button — is a 20th-century innovation. Until the 1980s, observant Muslims with savings had limited Shariah-compliant options: real estate, gold, private business equity, and very narrow ranges of bank products structured as profit-sharing.

The first modern Shariah-compliant investment vehicle of any meaningful scale was the Amana Mutual Funds, launched in the US in 1986 by Saturna Capital. Amana Income (1986) and Amana Growth (1994) applied early versions of the activity + ratio screen. As of 2024 they manage ~$5B and have produced returns roughly in line with US equity markets over multi-decade periods.

1999: Dow Jones Islamic Market index

The watershed moment for institutional halal investing was the launch of the Dow Jones Islamic Market Index in February 1999. For the first time, a major index provider ran a screening methodology documented and reproducible at scale. The DJ methodology used:

• Activity exclusions (alcohol, tobacco, pork, gambling, conventional finance, weapons, adult content)
• Three financial ratios capped at 33% — debt to market cap, cash + receivables to market cap, accounts-receivable to total assets

Other major indices followed: FTSE Shariah (2007), S&P Shariah (2007), MSCI Islamic (2007). Methodologies converged around the AAOIFI standard but with small differences in exact ratios and denominators.

Performance, briefly

Over multi-decade periods, broad Shariah-compliant indices have performed roughly in line with their conventional benchmarks — sometimes slightly better, sometimes slightly worse. The Dow Jones Islamic Market index has tracked the global equity market within ~1% annualized over rolling 10-year periods.

That said, the screen produces a meaningful sector tilt:

• Overweight: Technology, healthcare, consumer goods, energy.
• Underweight: Banks (excluded entirely), insurance, real estate (most REITs fail debt ratios), consumer discretionary with significant alcohol exposure.

This tilt is a feature, not a bug — but it does mean Shariah-compliant portfolios behave differently from broad markets in different cycles. In the 2000-02 dot-com bust, tech-heavy Shariah indices took larger drawdowns. In 2008, financials-free Shariah indices outperformed. Over the AI-driven 2023-2024, tech overweight was a tailwind.

AAOIFI's emergence

The Accounting and Auditing Organisation for Islamic Financial Institutions was founded in 1991 in Bahrain as Financial Accounting Organization for Islamic Banks (renamed in 1998). Its purpose: harmonize Shariah-compliance standards across the Islamic-finance industry, which until then had relied on fragmented and sometimes contradictory rulings from individual scholars.

AAOIFI publishes two streams of standards:

• Shariah Standards — religious-legal rulings on financial products. Standard 21 covers stocks and bonds; this is what Khabir's screen implements.
• Accounting and Governance Standards — financial reporting rules for Islamic banks and institutions.

AAOIFI is now adopted as a regulatory standard in 12+ jurisdictions (Bahrain, Oman, Qatar, Kuwait, UAE, Indonesia, Malaysia, etc.). When practitioners say "the AAOIFI standard," that's the document they mean.

Sukuk — the bond-like instrument that isn't a bond

Beyond equities, the other major Islamic-finance product is sukuk — often described as "Islamic bonds." Sukuk represent ownership of a real asset (a building, infrastructure project, fleet of equipment) that generates rent or lease payments, rather than ownership of a debt obligation that pays interest.

Sukuk became a serious global market in the 2000s. Outstanding global issuance grew from a few billion in 2003 to over $700B by 2024. Major sovereign issuers: Malaysia, Saudi Arabia, UAE, Indonesia, Turkey, the UK (which issued its first sovereign sukuk in 2014).

The 2008 sukuk crisis

The financial crisis tested the structural integrity of sukuk. The most prominent stress-test was Nakheel Sukuk — a $3.5B Dubai sukuk that approached default in late 2009 when Dubai World (the parent) requested a debt standstill. The market panicked over what "default" meant for an instrument structured as an asset-backed rental rather than a debt obligation. The eventual rescue by Abu Dhabi resolved the immediate crisis, but the episode revealed ambiguity in sukuk structures that hadn't been stress-tested.

Subsequent reforms (most notably AAOIFI's 2008 ruling on whether certain sukuk structures had been "true sale" or simply Islamic-labeled conventional debt) tightened the structural requirements. Modern sukuk markets are larger and more standardized than they were pre-2008.

Notable halal-compliant compounders

Long-term equity returns are dominated by a small number of compounders. Several have been Shariah-compliant for most or all of their public lives:

• Apple (AAPL) — Tech hardware, no debt issues for most of its history. Compliant since IPO. ~13,000% return from 2003 to 2024.
• Microsoft (MSFT) — Software giant, generally compliant though debt ratios occasionally drift near the 33% threshold. ~10× from 2010 to 2024.
• Costco (COST) — Consumer staples retailer. Shariah-compliant historically. Famously low debt, high ROE, durable competitive moat. ~20× from 2008 to 2024.
• Saudi Aramco (2222.SR) — World's largest oil producer, Shariah-compliant by design, listed in Riyadh 2019. Less compounder than dividend-yielding monopoly, but the largest Shariah-compliant company in the world by market cap.
• Tesla (TSLA) — Generally Shariah-compliant (electric vehicles, no obvious activity exclusions; debt ratios vary quarter-to-quarter). Major holding in many halal portfolios.

This is not a buy list. It's a historical observation: long-term compounders with halal-compliant fundamentals have existed in every era of US and global equity markets. Halal investing has not historically required giving up access to the best performers.

Where halal investing is going

Three trends to watch:

• ETF accessibility. US-listed Shariah-screened ETFs (HLAL, SPSK) are growing. As of 2024, HLAL has $400m+ AUM — small relative to the $7T US ETF market but on a steep growth trajectory.
• Robo-advisors with Shariah modes. Wahed (US/UK), Sarwa (UAE), Zoya (UK) provide algorithmic portfolio management with Shariah screens built in. Lowers the barrier for retail investors who don't want to pick individual stocks.
• ESG / Shariah convergence. Many ESG screens partly overlap with Shariah screens (no tobacco, no weapons, no gambling). The two frameworks are converging at the activity level, though they diverge on financial ratios.

Key takeaways

• Modern halal investing is ~30 years old as a structured practice. AAOIFI standards (1991+) are the canonical framework.
• Shariah-compliant indices have performed broadly in line with conventional benchmarks over multi-decade periods, with sector tilts that help in some cycles and hurt in others.
• Sukuk are bond-like instruments backed by real assets. The 2008 Nakheel episode revealed structural ambiguity that has since been tightened.
• Many of the best long-term equity compounders (AAPL, MSFT, COST, etc.) have been halal-compliant for most or all of their public history. Halal investors haven't historically had to give up access to top performers.
