Definition
Istisna (استصناع) is the classical Islamic contract for commissioning a yet-to-be-manufactured or built asset to defined specifications. The buyer (the mustasni') places an order with the seller-manufacturer (the sani'), specifying the asset to be produced; the manufacturer commits to deliver the finished asset in a defined timeframe. Payment terms are more flexible than salam — full payment at contract is not required; staged payments are permitted.
Istisna fills the gap that salam does not: long-duration construction or manufacturing where full upfront payment is impractical and the asset evolves through stages of production.
The four Shariah conditions
Per AAOIFI Standard No. 11:
- Specifications must be precise enough to remove gharar — quality, dimensions, materials, performance.
- The subject must be something that can be manufactured/built — not an existing asset that already needs only sale, and not something universal-fungible (which would be salam).
- The price must be defined — though staged payment schedules are allowed.
- The delivery timeline can be defined or left open, with clear right-of-cancellation if the manufacturer fails to deliver in reasonable time.
Crypto-relevance
Istisna is the structural backbone of certain tokenised real-asset infrastructure financing projects:
- Tokenised istisna sukuk for renewable-energy facilities under construction
- Tokenised pre-construction financing for real-estate developments structured as parallel istisna
Where the underlying is a genuine real asset being built, and the token represents proportionate ownership in the future asset's revenue, the structure can be Shariah-compliant.
What does NOT qualify: ICO tokens promising a future "platform" or "ecosystem" with vague specifications — the gharar is too severe, and the "manufacturing" of a software platform is too speculative to satisfy istisna's specification requirement.
HalalCrypto does not include istisna-style tokens in any current tier's universe because the available on-chain inventory of properly-structured tokenised istisna does not yet meet our liquidity and transparency thresholds.
Screening implication
For launch readiness, the practical lesson is that "future utility" is not enough. A project promising that a token will later power a network, fund a facility, or represent an asset still needs precise specifications, enforceable delivery duties, and transparent ownership rights before it can be treated as istisna-like. Until those elements are independently verifiable, HalalCrypto treats the token as speculative and outside the eligible universe. This conservative posture prevents marketing narratives from substituting for contract substance.
