The question of whether cryptocurrency is halal sits at the intersection of classical Islamic finance principles and a technology that didn't exist when those principles were codified. Scholars worldwide have been wrestling with it since Bitcoin's emergence, and opinions range from outright prohibition to conditional permissibility — sometimes from institutions with similar methodological starting points.
This guide synthesises the most authoritative published positions and explains the Shariah logic behind each conclusion, so you can evaluate them rather than simply accepting them.
The Three Prohibitions That Matter
Islamic finance is governed by three core prohibitions. Any analysis of cryptocurrency must evaluate it against all three simultaneously.
Riba — Interest
Applies to lending with guaranteed return. Spot cryptocurrency ownership does not inherently involve interest. However, lending protocols (Aave, Compound), staking that resembles guaranteed yield, and margin products introduce clear riba concerns.
Gharar — Excessive Uncertainty
Not all uncertainty is prohibited — commerce always involves risk. Prohibited gharar is uncertainty about the existence, delivery, or essential attributes of the object of a contract. Spot purchases of established assets with functioning networks sit differently here than token presales or perpetual derivatives.
Maysir — Gambling
Zero-sum speculation where one party's gain is another's loss. Short-dated speculation with no analytical basis, perpetual contracts used for leverage without hedging purpose, and casino-model DeFi protocols face the strongest maysir arguments.
What AAOIFI Says
The Accounting and Auditing Organisation for Islamic Financial Institutions (AAOIFI) issued Shariah Standard No. 62 on cryptocurrency in 2022 — the most detailed institutional ruling to date from a body whose standards are adopted by regulators in Bahrain, Jordan, Qatar, Sudan, and the UAE.
AAOIFI's key conclusions: cryptocurrency is a recognised form of mal (property) under Islamic law; Trading spot digital assets is permissible subject to conditions including adequate disclosure of the asset's characteristics, settlement in real assets or fiat, and absence of deception. Derivatives, margin trading, and perpetual contracts are prohibited. Mining is permissible provided it doesn't involve supporting a haram network.
The three-gate framework that emerged from this standard — legal recognition, underlying economic activity, and financial ratio screening — has become the practical basis for most institutional crypto screening.
The Saudi Permanent Committee Position
The Saudi Permanent Committee for Islamic Research and Fatwas issued a ruling identifying Bitcoin specifically as haram due to its use in illegal transactions, its extreme speculative volatility (characterised as approaching maysir), and its lack of backing by a sovereign or physical commodity. This position reflects a stricter application of the maysir prohibition.
It is worth noting that the Committee's ruling predates AAOIFI SS-62 and was focused primarily on Bitcoin as it operated in 2017–2019. The evolution of the ecosystem — particularly assets with identifiable utility and regulated exchange infrastructure — may not have been within scope of that ruling. Scholars who reach different conclusions today often cite this contextual limitation.
The Critical Distinction: Spot vs. Derivatives
Almost every major contemporary ruling draws a sharp line between spot ownership and derivative products. The Shariah logic is grounded in classical contract doctrine:
| Instrument | Ownership Transfer | Shariah View |
|---|---|---|
| Spot buy/sell | Immediate | Permissible (conditions) |
| Crypto ETF (spot) | Indirect but real | Majority: permissible |
| Futures / forwards | None — cash-settled | Prohibited (gharar) |
| Perpetual contracts | None — no expiry | Prohibited (gharar + maysir) |
| Margin / leveraged trading | Borrowed — riba | Prohibited (riba + gharar) |
| Options | Contingent, speculative | Majority: prohibited |
Why Instrument Type Isn't Enough
Even a spot purchase requires asset-level screening. A coin can be legally traded on a regulated exchange yet fail Shariah standards if its network's primary purpose is haram (gambling protocols, interest-bearing lending infrastructure) or if haram revenue exceeds tolerated thresholds.
The financial ratio threshold used by most Islamic screens — borrowed from AAOIFI equity screening — is 30%: haram-derived revenue must not exceed 30% of total network revenue. Some scholars apply a stricter 5% threshold. The right threshold depends on the madhab and the scholar's weighting of necessity (darura) arguments.

Summary of Key Findings
- ▸Spot ownership of established cryptocurrencies (Bitcoin, Ethereum) is conditionally permissible under AAOIFI SS-62 and the majority of contemporary institutional rulings.
- ▸Derivatives, margin, perpetuals, and options are prohibited across virtually all authoritative positions due to gharar and riba.
- ▸Asset-level screening is required regardless of instrument type — not all coins pass even for spot purchase.
- ▸The Saudi Permanent Committee's stricter ruling applies particularly to speculative trading behaviour, not necessarily to long-term ownership of utility assets.
- ▸Mining is generally permissible; staking is contested (guaranteed-yield staking leans haram, validator participation leans permissible).
- ▸Purification (removing haram-derived portions) is required for assets that partially fail revenue screening but fall below the threshold.
