Does Digitalization Change the Essence of Shariah Contract or Only Its Form?
The Essence of a Shariah Contract: Immutable Principles
A Shariah contract in Islamic finance rests on immutable principles: justice, transparency, prohibition of riba (usury), and asset-backing. These principles derive from the Quran and Sunnah and are not subject to change over time or means. Digitalization does not replace these foundations; it transfers them into a more efficient technical environment. The key is to ensure adherence to the core: the seller owns the asset, the buyer pays a fair price, and there is no riba or gharar (excessive uncertainty). The challenge is to ensure that digital applications do not compromise these principles under the guise of convenience.
The Form: From Paper to Blockchain
The form of the contract undoubtedly changes: traditional paper contracts have transformed into smart contracts on blockchains like Base. These contracts are open and auditable, offering unprecedented transparency. However, the new form must preserve the formal elements of a Shariah contract: offer and acceptance, specification of price and subject matter, and seller's ownership at the time of contract. Digitalization does not exempt these conditions; it facilitates their verification. For instance, a Qist contract ensures the seller owns the asset (e.g., an NFT or USDC balance) before the sale, and payment is immediate via the smart contract.
Achieving 'Seller Owns the Asset' Digitally
One of the most important pillars of an Islamic contract is that the seller must own the asset before selling it. In Bitcoin and digital assets, ownership is recorded on the blockchain. For digital assets like NFTs, ownership may be conditional on the smart contract. Therefore, in Qist we designed a mechanism to prove the seller's ownership at the time of the contract: the asset is linked to a unique Token ID in the contract, and the sale cannot execute unless the seller's address owns it. This makes the digital form precise and Shariah-compliant, rather than merely formalistic.
The Principle of Refunding Surplus in Digital Sales
In Islamic finance, if the price exceeds the allowable value of an asset, the surplus must be returned to the buyer. In traditional contracts, this is done manually. In Qist, we program the smart contract to calculate the difference between the sale price and the fair value (e.g., market average) and automatically refund the surplus to the buyer's wallet. This ensures the principle is applied without changing its essence: the seller cannot take what they do not deserve. Digitalization makes the refund faster and more accurate, yet does not alter the core Islamic ruling.
How Qist Implements This
Qist is a decentralized Islamic finance platform on Base committed to Shariah principles: the seller owns the asset (verified before listing), payment is in USDC (stablecoin), no riba or gharar (all contracts are predefined and audited), surplus is automatically refunded, and a 3-day grace period for the buyer. The contract is open on BaseScan for auditing. The Shariah essence remains unchanged, while the digital form enhances transparency and speed.
