Definition
Khiyar al-shart (خيار الشرط) is the classical fiqh term for a conditional option clause in a contract — a right one party retains to cancel the trade within a defined period. Classical fiqh allows khiyar al-shart in commodity sales under specific conditions (typically up to three days' inspection right). However, in monetary exchange transactions (bai' al-sarf), AAOIFI-aligned spot-trading principles explicitly excludes khiyar al-shart as one of the four conditions of valid sarf.
The reason is structural. Sarf requires immediate, complete, mutual transfer of possession (taqabudh). A conditional option clause allows one party to walk away after settlement — which contradicts the very point of the immediate-transfer requirement.
Why this excludes options contracts
A modern options contract — call or put — is the right but not the obligation to complete the exchange. The buyer of an option holds explicit khiyar al-shart: they can choose to exercise (complete the trade) or let the option expire (walk away). Where the underlying is a monetary or quasi-monetary asset (currency, crypto), the contract falls under the sarf framework, and khiyar al-shart is structurally excluded.
This is independent of the option's expiry, strike, or underlying. The structural defect is the right-to-walk-away clause itself. A 1-day option fails for the same reason a 1-year option fails.
Combined with the gharar problem (option pricing depends on volatility models the retail trader cannot fully audit) and the typical riba layer in option premium financing, options contracts fail at least three independent Shariah tests.
Why HalalCrypto does not trade options
The Shariah analysis combined with the operational reality means options are not even integrated into our infrastructure. The bot has no options API connection on any of the four supported exchanges. This is structural enforcement: a customer could not enable option trading even if they wanted to, because the integration does not exist.
For the comprehensive analysis of why every derivative type fails Shariah screening, see why we don't trade derivatives, futures, or margin.
In customer-facing terms, this is why "limited downside" option language does not solve the Shariah issue. The problem is not only that an option can be risky; it is that the paid right to decide later is itself the traded object. That right is incompatible with the immediate-exchange discipline required for crypto-as-sarf.
The safer retail rule is direct: if the product's value comes from a choice to exercise later, do not treat it as spot exposure.
