Mufti Muhammad Taqi Usmani, one of the most influential authorities in contemporary Islamic finance, ruled this month that cryptocurrency is not maal, not wealth, under Sharia. Buying anything with it, his fatwa holds, is not permissible, because a token is merely a record of notional numbers in an account. The ruling has done what few fatwas manage outside specialist circles: put a five-letter Arabic word on the front page of the financial press.
That question, is a token maal, matters, and it deserves the careful scholarly engagement it is already receiving from serious people on more than one side of it.
But it is not the first question. And treating it as the first question is why so much of the debate that followed Mufti Usmani's ruling goes nowhere.
Islamic finance was never built around a single word. It was built around six: riba, dayn, qard, bay', gharar, and maysir. Interest, debt, the loan, genuine exchange, uncertainty, speculation. These are not a checklist to run a token through after it already exists. They are the architecture Islamic law asks any monetary arrangement to have, or to lack, before wealth even enters the conversation. Test money itself against these six roots, classical metal through the newest protocol, and Mufti Usmani's ruling on any single token becomes a smaller, later question than the headline suggests.
The Six Roots, Briefly
Riba. From a root meaning to grow, increase, swell. An unjust increase secured on money through delay or through unequal exchange, forbidden absolutely and without appeal to intention.
Dayn. An outstanding obligation, sharing its root with din, faith, and dayyan, the Judge. A dayn that grows through delay is riba wearing a different name.
Qard. Literally, a piece cut from one's wealth and given to another, on the condition that only the exact equivalent returns. Any demanded increase converts a qard into riba.
Bay'. Genuine bilateral exchange. Two things moving in two directions, each side requiring real prior ownership, real risk, and real counter-value. Trade, in the Quran's own word for what riba is not.
Gharar. Excessive, avoidable uncertainty about a transaction's subject, price, or outcome, the ambiguity the law asks both sides to remove before they trade.
Maysir. Gain by pure chance at another party's necessary expense, a wager dressed as an exchange.
These six are the foundation this article tests money against, and testing money against them, rather than testing a token against the single word maal, is the argument this piece exists to make.
Testing Money's Architecture Against the Six Roots
A currency's relationship to riba, dayn, and qard is set the moment it is created, not the moment someone trades it. A currency's relationship to gharar and maysir is set by how transparent and how speculation-resistant its design is, not by whether any individual transaction happens to be honest. Applying the six roots at the level of architecture, rather than at the level of a single purchase, is what this section does across four candidates: classical metal, fiat currency, cryptocurrency in its distinct forms, and GX Protocol.
Classical metal
Gold and silver satisfy the six roots more completely than almost any instrument since. Nothing is created as dayn when a coin is minted; no debt attaches to its existence. A gold-for-goods trade is bay' in its clean, textbook form: real prior ownership, real risk, real counter-value on both sides. Quality is assayable and quantity is countable, which starves gharar of the ambiguity it needs. And because gold cannot be issued at will by anyone holding a printing press, the Cantillon-style speculation that riba and maysir both feed on has nowhere to attach itself at the point of creation.
What classical metal does not resolve is scale. A currency that satisfies five roots perfectly but cannot settle a modern economy's daily volume of exchange has solved the jurisprudence and left the economics undone. That gap is exactly where the next three candidates begin.
Fiat currency
Fiat fails these tests at the level of birth, not merely at the level of use, and it fails them in a way the classical jurists never had reason to anticipate.
Virtually all money in circulation today enters existence as a loan. A government spends beyond its revenue and a central bank buys the resulting bonds with newly created money; a business or household borrows and a commercial bank creates a deposit that did not exist a moment before. This is dayn at the root: money is born already carrying an obligation, and because interest accrues on that obligation, the system requires more money to exist in total claims than exists in total supply. That is riba built into the currency's birth certificate, not merely available as an optional sin at the point of lending.
The qard test fails for the same reason from the other direction. A qard is a piece cut from wealth on the condition that only its exact equivalent returns. Fiat is engineered to return less than it borrowed, by design: the US dollar has lost roughly 87% of its purchasing power since 1971. The Turkish lira lost roughly 80% of its value between 2018 and 2024. The Lebanese pound collapsed by around 90% between 2019 and 2023. A currency that reliably returns less value than it received is not a qard honoured. It is a qard broken by policy, at scale, continuously.
Gharar and maysir arrive together, through what economists call the Cantillon effect. New money is not distributed evenly; it reaches asset holders and financial institutions first, at today's prices, before wage earners see it in their pay packets, by which point prices have already moved. Three centuries of economic literature have named this effect without ever prescribing a remedy for it. Stripped of its technical vocabulary, first-round recipiency is a structural information asymmetry (gharar, at the scale of an entire monetary system) that transfers wealth from the last to receive toward the first (a wager the ordinary saver never agreed to enter, which is the shape, if not the letter, of maysir). Global household debt reached approximately USD 59 trillion in 2024. Payday lending in some markets runs 300 to 500% APR. None of this is an accident inside an otherwise sound design. It is what a debt-born, riba-bearing currency produces when it is scaled to a planet.
Cryptocurrency, tested by type
Bitcoin, stablecoins, and utility or governance tokens fail and pass the six roots in different places, which is exactly why treating "crypto" as one instrument obscures more than it reveals.
Bitcoin's supply schedule is genuinely free of riba and dayn at the protocol level: nothing is owed, nothing compounds, and no authority can dilute it by decree. But scarcity alone does not satisfy gharar and maysir. Bitcoin's price is dominated by speculative trading rather than by use in genuine bay', which is a maysir concern the classical jurists would have recognised instantly even without the word blockchain. And its own defenders rarely mention the second failure: an estimated three to four million coins, roughly a fifth of everything ever issued, are already permanently irrecoverable behind lost keys, with more lost every year and none ever recovered. A currency whose stock can only shrink rewards holding and punishes spending, which is not a medium of exchange achieving bay'. It is a hoarding instrument with a settlement layer attached.
Stablecoins inherit whatever they are pegged to, which in practice means they inherit fiat's riba and gharar rather than escaping them. A token backed by interest-bearing reserves carries riba once removed. A token whose redemption claim cannot be independently verified carries gharar in a new wrapper. Digitising the ledger does not purify what sits beneath it.
Utility, governance, and security tokens were never offered as money in the first place; they are closer to a share or an access right. Testing them against the six roots at all is close to a category error, and it is the exact imprecision a blanket ruling on "crypto" risks committing.
GX Protocol
A protocol that claims to have been architected around these roots, rather than screened for them afterward, deserves to be tested against all six in turn, and this is where the case can be made with the most confidence, because it is a case about design intent stated in public and checkable against a published specification.
Riba, dayn, and qard are addressed at the point of creation, which is the only point that matters given the analysis above. GX units are not lent into existence; they are granted, from a supply fixed permanently at 1.25 trillion, with no code path for creating more. The protocol's lending pools operate on profit-and-loss sharing terms with interest prohibited as an immutable rule: a business that succeeds returns a share of profit; a business that fails after a demonstrated, sustained inability to repay has half its remaining principal forgiven after ten years. Capital is a qard honoured or a loss shared, never a riba compounded.
Bay' is the protocol's only stated purpose. GX is explicitly designed as a medium of exchange rather than a speculative asset, to the point of forgoing an exchange listing altogether, on the reasoning that a tradable market price would turn the unit into something to be sold rather than something to be traded with. This is the same distinction the protocol's own literature draws between the fiqh of assets and the fiqh of money: an asset's value is what it can be sold for; money's value is what it can buy. GX is built to remain the second thing.
Gharar is addressed by radical transparency rather than by disclosure after the fact. The supply cap, the distribution formula, the velocity schedule, and the lending terms are published and enforced in code that anyone can inspect, not held as discretionary policy subject to revision. The protocol's own soundness self-assessment states its confidence at approximately 88%, not 100%, and publishes the gap rather than hiding it, which is a stranger and more honest thing for a monetary system to do than almost any incumbent has ever done.
Maysir is resisted structurally, not just discouraged by sentiment. Beyond the absence of a tradable listing, a velocity mechanism applies a rising charge, from 3% to 6% across eight balance bands, to surplus left idle above GX 100 for a completed 360-day cycle, while every balance up to that threshold is permanently exempt. The charge does not fall on income earned and spent within a cycle. It falls only on accumulation that has stopped moving, which is the precise target the classical concern with hoarding, iktinaz, was always aimed at.
The protocol's own published framework calls this the lifecycle theory of money: the claim that a monetary constitution must govern not only how much money exists but how it is created, distributed, circulated, productively deployed, accumulated, and recycled, because outcomes are set at every one of those stages, not only at the first. Read against the six roots, the parallel is close to exact. Creation and distribution are where dayn and qard are honoured or broken. Productive deployment is where riba is refused or admitted. Circulation and accumulation are where maysir either finds a foothold in hoarding and speculation or is denied one. The two frameworks, one classical and Arabic, one contemporary and architectural, are asking versions of the same question from different centuries.
None of this is offered as proof against every objection. GX Protocol is presently a working reference implementation on a development network, not a production system with years behind it, and the honest answer to how it performs at global scale is that performance has not yet been observed, only designed for and staked in public, falsifiable form. What can be said with confidence is narrower and still substantial: this is a monetary architecture that was tested against the six roots at the drawing board, not one built first and defended after.
| Root | Classical metal | Fiat | Bitcoin | Stablecoins | GX Protocol |
|---|---|---|---|---|---|
| Riba | Absent at creation | Present at creation; money born as interest-bearing debt | Absent at protocol level | Inherited from backing reserves | Prohibited as an immutable rule; profit-and-loss sharing only |
| Dayn | None created by issuance | Structural; more claims than money in existence | None created by issuance | A redemption claim on the issuer | Grant-born, not debt-born |
| Qard | N/A; not a lending instrument | Broken by design; value reliably returns less than received | N/A; not a lending instrument | N/A; not a lending instrument | Principal-only returns; partial forgiveness on genuine hardship |
| Bay' | Satisfied; real ownership, real risk | Frequently satisfied in use, though origin is credit | Satisfied in genuine purchase; strained by speculative volume | Satisfied in genuine purchase | The protocol's stated sole purpose; no exchange listing by design |
| Gharar | Low; quality assayable, quantity countable | High; value by decree, no published ceiling | Moderate to high; price volatility | Moderate; reserve claims often unverified | Low; rules published and enforced in code |
| Maysir | Low, historically | Indirect, via the Cantillon effect | High in practice; dominant use is speculative | Lower; designed to track, not swing | Structurally discouraged; velocity charge on idle surplus |
Where the Fatwa Actually Lands
Once money's architecture has been tested this way, the fatwa's real scope comes into focus, and it is narrower than the headline suggested.
The ruling in question, issued by Darul Ifta at Jamia Darul Uloom Karachi and signed by Mufti Muhammad Taqi Usmani alongside five other scholars, responded to a specific query about purchasing books with cryptocurrency, including USDT. Its finding was that the tokens involved do not meet the threshold of maal, recognised property, and are better described as a record of notional numbers in an account. It extended that reasoning across Bitcoin, Ethereum, and stablecoins alike, on the basis that relabelling a token does not change what it is.
That is a serious, carefully reasoned position, and it is one position among several. Egypt's Dar al-Ifta reached a similar conclusion under Grand Mufti Shawki Allam, citing gharar and the absence of a recognised issuing authority. The Syrian Islamic Council ruled similarly in 2019. On the other side, South African authorities including Darul Uloom Zakariyya, and scholars such as Mufti Radha ul-Haqq and Shaykh Taha Karaan, hold that Bitcoin can qualify as maal through urf, communal acceptance, the same mechanism by which printed paper became money in the first place. Malaysia's Securities Commission recognises digital assets as property, subject to screening. Dr Monzer Kahf treats Bitcoin as commodity-like, its value drawn from social consensus. Mufti Usmani's own past writing leaves room for his position to shift if a cryptocurrency comes to be used in genuine trade by a genuine economy rather than remaining dominated by speculation.
The International Islamic Fiqh Academy, notably, has already reached this article's conclusion on independent grounds: it has issued no single ruling on "crypto," splitting digital assets instead into those backed by fiat, those backed by precious metal, and decentralised coins with no backing, treating the first two as relatively uncontroversial and reserving genuine scrutiny for the third. In Pakistan itself, Bilal Bin Saqib, chairman of the Pakistan Virtual Assets Regulatory Authority, met with Mufti Usmani shortly after the ruling and described a constructive discussion grounded in a shared aim of protecting citizens from fraud, while stressing that digital assets span a genuinely broad range of technologies deserving individual technical and Shariah assessment rather than a single blanket lens. That is the direction this article has argued for throughout: classify the instrument by its actual design, then test it, rather than testing the word.
None of this settles which position is correct on any specific token, and that verdict belongs to qualified scholars, not to this article. What the six-roots test does is relocate the disagreement to where it actually lives: not whether a cryptocurrency can be exchanged for value, which plainly some can, but whether a specific instrument's design, tested at creation and in use, clears the bar classical jurisprudence set for recognised property. That is a narrower and more answerable question than the one the headline posed.
Money, Currency, Wealth: The Words Beneath It All
The case above rests on three words that are worth defining precisely, even briefly.
Money is the social institution: the shared agreement that lets a community exchange, measure, store, and settle value using a recognised medium. Currency is the instrument, the specific coin, note, or protocol used to perform that function; not every currency performs it equally well, which is the entire reason a test is needed. Wealth, maal, is broader than either: land, a trade, a skill, a harvest. Money is one way of carrying a portion of one's wealth from one moment to the next. It is not wealth in itself, and a currency's fitness to carry value is a question about its design, answerable through riba, dayn, qard, bay', gharar, and maysir, not a question that the single word maal can carry alone.
This is also the proper location of the Mizan diagnostic, which formalises exactly this six-part test for any financial arrangement, drawn from two companion studies on the blog: one tracing riba, dayn, qard, and bay' to their roots in the primary sources, the other extending the same rigour to gharar and maysir. Mizan asks the question one level closer to a transaction than this article has: given an arrangement, does it clear the six roots. This article has asked the question one level further back: given a form of money, does its architecture clear them before any transaction using it even begins. Both questions matter, and answering the second well is what makes the first worth asking of anything built on top of it.
The Question Worth Carrying Forward
Is a given token maal is a real question, and it deserves the primary-source rigour scholars are already giving it. But the six roots were never written for tokens. They were written for money itself, and they apply to every form it has ever taken, gold, paper, decree, and code, with no exceptions carved out for the instrument we already trust out of habit.
Test money's architecture against riba, dayn, qard, bay', gharar, and maysir before asking whether any single unit of it is wealth, and the fatwa stops being the whole conversation and becomes what it always was: one careful ruling on one category of instrument, inside a much older and much larger question about what money is allowed to be.
Any conclusions of a jurisprudential nature in this piece belong to the scholars equipped to reach them. Any errors in the argument are mine alone.
