1. The Concept of Signing a Transaction in Islamic Finance
In Islamic finance, signing a transaction is not merely a formality; it is a confirmation that the contract adheres to Shariah principles: real ownership, absence of riba (usury) and gharar (excessive uncertainty), and transparency. The signature indicates that all parties have agreed to the terms after understanding them, and that the asset has legally transferred to the buyer before any subsequent sale. This prevents selling what you do not own and ensures fairness.
2. Difference Between Digital and Traditional Signatures in Islamic Finance
In decentralized Islamic finance, signing is done via digital wallets using private keys, proving ownership without a middleman. This aligns with the principle of "free contracting" provided the contract is clear and free from manipulation. Digital signatures enhance transparency and reduce gharar as they are permanently recorded on the blockchain.
3. When is a Signature Valid Shariah-Wise?
A signature is valid when the contract is free from riba and gharar, the asset is actually owned by the seller, and there is no condition on an unknown event. The parties must have legal capacity, and the subject matter must be known and deliverable. In Qist, this is ensured through direct sale and murabaha.
4. Cases Where Signing Should Be Refused
Signing should be refused if the contract contains a usurious condition (e.g., late payment penalties), the asset is not owned by the seller (gharar), there is coercion, or the price or term is uncertain. Also, it is refused if the contract involves selling debt for debt. Qist automatically prevents these via smart contracts.
5. How Does Qist Implement This?
Qist ensures that every financed transaction is a real sale of an asset (e.g., commodities) before any transfer of ownership. Users sign with USDC on a smart contract following murabaha: Qist buys the asset, sells it to the buyer on installments with a fixed profit margin. Any attempt to sign a non-compliant contract is automatically rejected. The 2% fee and surplus refund ensure fairness. The contract is auditable on BaseScan.
