Why the business itself matters
A clean balance sheet cannot rescue a business that should not be owned. This is the screen that runs first.
This module covers rules and obligations specific to Muslim investors. If that's not relevant to you, the surrounding modules still work on their own.

The next module will argue that buying a share is buying part-ownership of a real business. Accept that for a moment and a conclusion follows immediately: if owning the business would be a problem, owning part of it is a problem, and the size of your slice does not change the character of what you own.
That is the entire logic of the business-activity screen. It is applied first, before any financial ratio, and it cannot be offset. A pristine balance sheet does not rescue a casino.
The excluded categories
A screening standard (a published methodology for testing whether a company's business and finances are Shariah-compliant) is what turns the principles from the last two lessons into an actual pass or fail. The categories below are consistent across the three major ones, AAOIFI, S&P Dow Jones Islamic Market and MSCI Islamic. The standards diverge on the financial ratios, not on this list, and the Shariah-compliant vehicles lesson compares them properly.
| Category | Why, and the Australian shape of it |
|---|---|
| Conventional banking, insurance and interest-based finance | The revenue is the riba (the extra charged for the use of money), or in the insurance case the gharar (uncertainty so severe the contract is really a guess) structure from the previous lesson. This is the single biggest exclusion on the ASX by market value: the major banks are several of the largest listed companies in the country, plus the insurers and the non-bank lenders. |
| Alcohol production or retail | Production, distribution and retail. This is why Coles is excluded outright on the ASX, through Liquorland and licensed venues, while a supermarket without a liquor arm would be assessed differently. |
| Gambling and wagering | Operators, venues, and the suppliers whose product exists only for gambling. On the ASX this captures the wagering operators and the gaming machine manufacturers. |
| Pork and non-halal food production | Assessed on the production and processing side rather than on a supermarket carrying a category. |
| Adult entertainment | Production and distribution. |
| Weapons and tobacco | Tobacco is straightforward. Weapons is the category that generates the most genuine judgment calls on the ASX, because defence contracting sits on a spectrum from communications equipment to ammunition. |
Why a threshold exists at all
A reasonable objection: if the principle is that you should not own a prohibited business, why do the standards tolerate any exposure at all? Why not zero?
Because zero is not a standard, it is an exit from public markets entirely. Nearly every large listed company holds cash somewhere that earns interest, carries some debt, or has a subsidiary with a revenue line nobody at head office thinks about. A rule of absolute purity would exclude everything, which is not a stricter interpretation of the principle, it is the abandonment of the attempt to apply it.
So the standards separate two different questions:
- What is the business for? This is qualitative, binary and not negotiable. A casino is for gambling. No percentage changes that.
- How much unavoidable contamination is being carried? This is quantitative, and it is where thresholds do their work. AAOIFI's income test caps impermissible income at 5% of revenue, with the balance-sheet ratios covered in the Shariah-compliant vehicles lesson.
The Islamic Foundation module's tayyib (good and wholesome, not merely permitted) lesson made the same point from the other direction: the screen is a floor, and the floor is the easy part.
The grey edges, which are where the real work is
Four patterns produce almost all the hard cases.
1. Diversified conglomerates
A company that operates in eight unrelated industries is eight judgment calls, and the segment reporting may not separate them the way the screen needs. This is why Wesfarmers carries a review verdict on the site's own screener rather than a clean pass, despite comfortable ratios: the ratios are not the hard part, the segment mix is.
2. Suppliers and landlords
A company that manufactures gaming machines does not operate a casino, but its product exists for gambling. A shopping centre landlord whose tenants include a bottle shop is a step further removed again. How far down the supply chain the prohibition reaches is a genuine question, and the standards draw the line in slightly different places.
3. Defence
The exclusion is straightforward for an ammunition manufacturer and much less so for a company supplying tactical radios, or a shipbuilder building naval vessels alongside commercial ferries. The site's screener marks several of these as review rather than pass or fail, because that is an honest description of the state of the question, not a hedge.
4. Interest income as the actual business
The subtlest one, and it does not look like a business-activity problem at first. A pre-revenue mining explorer holding $180 million of cash from a capital raise, with almost no product revenue, may be earning nearly all of its reported income as interest on term deposits. Its debt and cash ratios can look clean while the income test is the one that bites. The Shariah-compliant vehicles lesson returns to this when it covers screening mechanics.
How to actually assess a company
- Read the segment breakdown in the annual report, not the marketing. Revenue by segment is a disclosed number and it is the only thing that settles what the business actually is.
- Ask whether the problematic part is incidental or structural. The three questions from the tayyib lesson apply directly here.
- Check whether the company itself discloses the problematic line as a metric. If a company reports something like margin income as its own headline figure, it is telling you that line matters to its business model.
- Accept that some companies are genuinely unresolved. A review verdict means the ratios did not decide it and the business mix needs a judgment you should make with your own scholar, not one a screener can make for you.
The financial half of the screen, the debt, cash and receivables ratios and where the 30% figure comes from, is the Shariah-compliant vehicles lesson. The full criteria with primary sources are on the Methodology page.

4 questions on this lesson. Nothing is recorded or sent anywhere.
1Why is the business-activity screen applied before the financial ratios?
The qualitative test is binary and not negotiable. A clean balance sheet does not rescue a casino.
2Why do screening standards use thresholds instead of demanding zero exposure?
The standards separate what the business is for, which is binary, from how much unavoidable contamination it carries, which is where thresholds do the work.
3A pre-revenue mining explorer has near-zero debt, a large cash pile and almost no product revenue. What is the likely screening problem?
This is the subtlest of the four grey-edge patterns and it is why a clean-looking ratio screen is not by itself a verdict.
4What does a review verdict on the site's screener mean?
Review is an honest description of an unresolved question, not a soft fail. Wesfarmers carries one for exactly this reason despite comfortable ratios.
