Riba, gharar and maysir, explained for savers

The short answer

Islamic finance rests on three prohibitions that apply to almost every saving and spending decision. Riba is interest. Gharar is excessive uncertainty. Maysir is gambling. A product that avoids all three is not automatically halal, because scholars also ask what the money funds, but one that fails any of them raises a clear flag. Fasset applies these tests in its guide to what makes a coin Shariah-compliant; this article explains the ideas for anyone managing everyday money.

These are concepts, not rulings. Where scholars disagree, this guide says so rather than choosing a side.

Riba: interest and unequal exchange

Riba literally means increase. In finance it covers two things. The first is any excess a lender stipulates on a loan, which is what conventional interest is. The second is an exchange of the same kind of item, such as money for money, in unequal amounts or with delivery deferred.

For a saver, the first meaning matters most. A savings account that pays a stated rate is a loan from you to the institution, and the rate is the stipulated excess. A deposit that shares in the actual results of a venture, with no promised return, is structured differently. That is why the label on the payment, whether profit, reward or yield, tells you little. Read the terms and ask whether a return is promised in advance.

The second meaning is why scholars care about possession. AAOIFI Shari'ah Standard No. 1, on currency exchange, requires both sides to take possession before they part and bars forward and futures deals. Fixed-rate earn products on crypto raise the first meaning directly, as the guide on whether staking is halal explains.

Gharar: excessive uncertainty

Gharar is uncertainty about what is being exchanged: its existence, quantity, quality, price or whether it can be delivered. Every contract has some uncertainty, so scholars generally treat only excessive gharar as invalidating a contract, and they differ on where the line falls.

It helps to separate gharar from risk. Risk is that an asset's value may fall. Gharar is that you may not know what you are buying, or that the seller can change the terms or cannot deliver. Whether price volatility itself amounts to gharar is disputed, and the debate over stablecoins in is USDT halal shows how scholars weigh this.

Practical red flags for a saver include terms that can change without notice, withdrawal restrictions that are unclear, and a product whose underlying assets are not described.

Maysir: gambling

Maysir, also called qimar, is a stake on an uncertain outcome where one party's gain is the other's loss and nothing productive is exchanged. Lotteries and betting are the plain cases.

The test also reaches financial products that work the same way. A contract that pays only the difference between two prices, without delivery of the asset, is treated by many scholars as a wager. Leverage and short-dated speculation raise the same question. If a product is marketed on the thrill of a win rather than on the use of the asset, treat that as a flag.

The three side by side

Questions a saver can ask

1. Is any return promised or stated in advance, whatever it is called?
2. Can the provider change the terms without telling me, and can I withdraw when I choose?
3. Do I receive the asset I think I am buying, or only a price difference?
4. What does the provider do with my money, and who holds it?
5. Who reviewed this product for Shariah compliance, by what method and on what date?

For a USD balance, the guide on how a USD account works explains what the account is and who holds the money. Costs belong in your assessment too, and Fasset lists its charges on its fees page.

What a label does not prove

A halal label is a claim by whoever issued it. It is as reliable as the named reviewer, the method and the date behind it, and scholars may disagree with it in any case. Fasset's About page says every account, service and investment is delivered without interest. That speaks to the riba test only. It does not on its own settle gharar, maysir or the lawfulness of what the money funds, and Fasset has not yet published a Shariah board or certificates. Treat that as information to weigh, and use the steps in how to screen a coin yourself to check the rest.

A regulatory licence is likewise not a Shariah ruling. Fasset FZE holds a VARA VASP Licence for Broker-Dealer Services, reference VL/23/07/002, issued on 30 November 2023, covering activity carried on in or from Dubai. That is supervision of a firm. Fasset is not a bank. Balances are not bank deposits and are not covered by a deposit guarantee scheme. For wider context, see is crypto halal and the Fasset FAQ.
