Definition of Murabaha in Islamic Finance
Murabaha is a sale contract where the seller discloses the original cost of the asset to the buyer and then adds an agreed profit margin. It is one of the most important Islamic financing contracts, where the financier (seller) purchases the asset upon the buyer's request and then sells it to the buyer at cost plus a known profit. The asset must exist and be owned by the seller before sale, and the price can be paid in installments or deferred. This contract is free from gharar (uncertainty) and riba (usury), as there is no compound interest or hidden costs. According to the Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI), the profit must be fixed and known to both parties at the time of contract.
How Murabaha is Executed on Blockchain
On the blockchain, Murabaha is implemented via smart contracts that replicate the traditional steps. First, the seller (financier) lists the asset - for example, a token representing a real asset - in a smart contract, along with the cost. The buyer then requests to purchase, and the contract transfers ownership in exchange for deferred or installment payments in USDC. Each step is recorded on-chain: seller's ownership, cost disclosure, profit agreement, and asset transfer. This ensures transparency and reduces gharar, as any party can audit the transaction on a block explorer like BaseScan. The smart contract enforces the seller to disclose the cost and ensures the profit is predetermined as a fixed amount or percentage.
Advantages of Murabaha on Blockchain vs Traditional
Murabaha on blockchain offers complete transparency, as all details - cost, profit, dates, parties - are immutably recorded. This reduces disputes and builds trust between strangers. Smart contracts also cut administrative costs and speed up the process by eliminating intermediaries. Crucially, Sharia compliance - such as the seller owning the asset and absence of gharar - can be coded into the contract, making it unbreakable. For instance, the contract verifies the seller actually owns the asset before proceeding. Additionally, the 'surplus refund' mechanism ensures no unfair gain for the financier beyond the agreed profit.
Challenges and Solutions for Digital Murabaha Sharia Compliance
The main challenge is ensuring the asset is real and fully owned at the time of sale. On public blockchains, assets may be purely digital, so compliant tokens like NFTs representing physical assets or stablecoins backed by real collateral are used. Second, proving the stated cost is correct can be solved by providing off-chain proofs (e.g., invoices). Late payment fees are addressed via a '3-day grace period' without riba penalties. Also, the smart contract must avoid any form of manipulation or 'electronic fraud', which is achieved through public audit by both Sharia scholars and technologists.
How Qist Implements This
The Qist platform fully implements the Murabaha contract on the Base chain. The seller owns the asset - digital or representing a real asset - and lists it with the purchase cost. The buyer pays in installments using USDC, with a 3-day grace period for late payments without riba fees. If the contract generates a surplus (e.g., selling above market price inadvertently), the surplus is returned to the buyer per the fairness principle. Every transaction is recorded on-chain and auditable via BaseScan, ensuring transparency and Sharia compliance. Platform fees are only 2% covering operational costs, and we adhere strictly to no riba or gharar. Discover Qist for decentralized Islamic finance.
