Insurance is one of those sectors where Muslim investors sometimes assume "it's probably fine, right?" because the business doesn't feel as obviously non-compliant as a casino or a liquor brand. A company pays claims when something bad happens. Seems helpful. Seems sensible. Seems Islamic even.

Then you look at how the product is actually structured and it turns out conventional insurance breaks at least three foundational rules of Islamic commercial law at once. That's a record.

Let's walk through why AIG, Prudential, Allianz, and the rest of the big insurers are universally rejected by Shariah screening boards, what the specific problems are, and where takaful fits into the picture.

The three sins of conventional insurance

Shariah scholars have been discussing insurance since the mid-1800s when European insurance started showing up in Muslim-majority markets. The consensus that emerged from the OIC Fiqh Academy in 1985 (and has been reaffirmed many times since) is that conventional insurance involves three major problems:

1. Gharar (excessive uncertainty). In a conventional policy, you pay a premium but you have no idea whether you'll get anything back. The contract is essentially a bet on whether a bad thing happens. If the house burns down, you collect. If it doesn't, you don't. That level of uncertainty in a commercial exchange violates the prohibition on gharar fahish (excessive, contract-invalidating uncertainty).

2. Riba (interest). The insurance company takes your premium and invests it in interest-bearing instruments. That's basically the entire business model for life insurers. Float goes into bonds, bonds pay coupons, the company keeps the spread. The core investment portfolio is riba-based.

3. Maisir (gambling). Because the policyholder might get back much more than they paid in (or nothing at all), the contract has a zero-sum gambling structure. You're betting against the insurer, the insurer is betting against you, and one of you loses.

Three violations, one product. That's why Shaykh Mustafa Zarqa, Shaykh Yusuf Al Qaradawi, and the OIC Fiqh Academy all landed on the same conclusion: conventional insurance, in its current form, is not permissible, and neither are the stocks of conventional insurers.

AIG (NYSE: AIG) by the numbers

American International Group is a pure-play conventional insurance giant with some investment and retirement products on the side. Here's what the screening looks like:

Sector test: Fail immediately. The core business is conventional insurance underwriting. Non-permissible income is effectively 100 percent of operating revenue. The 5 percent tolerance doesn't touch this.

Debt-to-market-cap: AIG's long-term debt sits around $21 billion against a market cap of roughly $52 billion. That's about 40 percent. Above the 30 percent threshold. Fail.

Cash and interest-bearing securities: This is where insurers get absurd. AIG holds well over $200 billion in investment assets, the vast majority in fixed income (bonds, government securities, mortgage-backed instruments). The ratio of interest-bearing securities to market cap is somewhere around 4x or higher. Fail by a mile.

Receivables: Premium receivables and reinsurance recoverables push this ratio above threshold too. Fail.

Four screens, four fails. And this is a name people sometimes bring up as "maybe okay" because of its commercial focus. It isn't.

Prudential Financial (NYSE: PRU)

PRU is a life insurance and retirement products giant. Life insurance is particularly problematic in Islamic finance because the entire economic model depends on investing customer premiums at interest for decades.

Sector test: Fail. Core business is life insurance, annuities, and retirement. Every single line of business is built on conventional insurance structures.

Debt-to-market-cap: Long-term debt around $20 billion against market cap of ~$43 billion. Right at 47 percent. Fail.

Interest-bearing securities ratio: Prudential runs a ~$700 billion general account portfolio, overwhelmingly in fixed income. Completely unrecoverable ratio. Fail.

Non-permissible income: Interest and investment income are the dominant earnings source alongside underwriting premiums. Well above any threshold. Fail.

It's also worth flagging that Prudential PLC (UK-listed PRU:LON) is a separate company from Prudential Financial despite the shared name. Same result though. Both fail.

Allianz SE (XETRA: ALV)

The largest European insurer. Property, casualty, life, asset management. Giant.

Sector test: Fail. Multi-line conventional insurer.

Financial ratios: Allianz carries meaningful debt and holds enormous investment assets, primarily in sovereign and corporate bonds across Europe. The interest-bearing securities ratio is well above threshold. Fail.

Non-permissible income: Between premiums from riba-backed products and investment income from fixed income, this is effectively a non-permissible business from top to bottom.

One thing that sometimes comes up with Allianz: they own PIMCO, one of the biggest bond managers in the world. Whatever you think of PIMCO's products, they are literally in the business of bond management. The riba exposure isn't a side effect. It's the whole point.

The other usual suspects

Same story, different logos:

MetLife (MET): US life insurance and employee benefits. Fails all four screens.
Chubb (CB): Commercial P&C. Sector fail; financial ratios also fail.
Travelers (TRV): Same.
Progressive (PGR): Auto insurance specialist. Fails sector and ratios.
Berkshire Hathaway (BRK.B): This is the one that trips up a lot of Muslims. Berkshire owns GEICO, General Re, and a massive insurance float that Buffett invests in everything from corporate bonds to equity stakes. Conventional insurance is a core business. Plus Berkshire owns stakes in multiple non-compliant businesses (banks, alcohol, others). It fails the sector and financial screens. I wrote a longer piece on the Berkshire question specifically but the answer is: no.
Zurich Insurance Group (ZURN): Swiss giant. Same result.
AXA (CS.PA): French giant. Same.

If you want to know whether any given insurer passes screening, the short answer is basically always "no." The slightly longer answer is "unless it's a takaful company."

Takaful: the actual Islamic alternative

Takaful (which comes from the Arabic word for "mutual guarantee") is the Islamic alternative to conventional insurance. The structure is fundamentally different:

Participants contribute money to a shared pool. The contribution is a tabarru (donation) to help others in need, not a premium that purchases a return guarantee.
Claims are paid from the pool. Surplus at year-end is either returned to participants or rolled forward.
The takaful operator manages the pool in exchange for a fee (wakalah model) or a share of underwriting surplus (mudharabah model), not by speculating on claims.
The pool is invested only in Shariah-compliant assets. No bonds. No conventional bank deposits. Sukuk and halal equities only.

Because it's based on mutual cooperation rather than a speculative bilateral contract, takaful eliminates the gharar and maisir problems. And because the investment side is restricted to halal assets, riba is gone too. Three problems solved.

Listed takaful companies exist in several markets:

Syarikat Takaful Malaysia (STMB) on Bursa Malaysia
Abu Dhabi National Takaful (TKFL) on ADX
Islamic Arab Insurance Co (Salama) on DFM
Bahrain National Holding (has takaful subsidiary, mixed structure)

If you want insurance sector exposure in your halal portfolio, these are where you look. Not AIG, not Allianz, not Prudential.

"But I need auto insurance. Is that non-compliant too?"

Different question. Different answer. Buying a policy because your state requires it or because you genuinely need risk coverage is usually treated differently from investing in the insurance company as a shareholder.

Most contemporary scholars (including Shaykh Muhammad Taqi Usmani) take the view that when takaful is not reasonably available, purchasing conventional insurance out of genuine necessity (darurah) is permissible, though buying the minimum required coverage is preferred. But that's a completely separate ruling from "should I own AIG stock." The first is about a consumer under duress. The second is about choosing to participate as an owner in a business whose model violates multiple rules of Islamic commerce.

You can use conventional insurance under necessity and still refuse to own the stock. There's no contradiction.

The bottom line

Conventional insurance companies are out. Not on a technicality, not on one ratio. They fail the sector test because the product itself contains three simultaneous violations of Shariah commercial law. They fail the financial ratios because their entire business is based on holding enormous pools of interest-bearing securities.

AIG, Prudential, Allianz, MetLife, Chubb, Travelers, Progressive, Zurich, AXA, Berkshire, and every other major name in the space are universally rejected by every mainstream Shariah screening methodology.

If you want insurance exposure in your portfolio, look to listed takaful operators in Malaysia, the UAE, and Bahrain. If you just want to know which names in your current portfolio have quietly slipped insurance exposure past you, run them through FaithScreener and you'll see the financial ratios and sector flags laid out cleanly.
