Definition
Ariyah (عارية) is the classical Islamic contract for the gratuitous loan of an asset for temporary use. The lender (the mu'ir) lets the borrower (the musta'ir) use a specific asset for a defined period, after which the same asset is returned. Critically:
- No fee is charged for the use (otherwise it becomes ijarah)
- The same physical asset is returned (not a fungible substitute, otherwise it becomes qard)
- The borrower can use the asset but cannot consume or alter it irreversibly
Ariyah sits between wadiah (custody, no use right granted) and ijarah (paid use). It is one of the foundational charity contracts in classical fiqh and is encouraged as an act of mutual aid.
Why this matters for crypto
Ariyah-style structures appear in some on-chain contexts:
- Lending an NFT for use (e.g., gaming character rentals where the NFT is returned afterward) — could be ariyah if no fee is charged. If a fee is charged, it becomes ijarah, and the rules of ijarah apply.
- Token gating with return obligation — some governance protocols require holders to "lend" tokens for voting power and return them after a vote. If gratuitous, ariyah-like.
What does NOT qualify as ariyah:
- DeFi "lending pools" that accept tokens, mix them with other deposits, lend them to other users, and return a different fungible quantity later. The structural identity is qard (loan of fungible value), not ariyah, and where the return exceeds the deposit, riba applies.
- Liquid staking where the staked asset is replaced with a derivative token (e.g., stETH) — this is a qard-with-substitute, not ariyah.
Why HalalCrypto's relationship to customer assets is not ariyah
A common analytical confusion: "is HalalCrypto borrowing the customer's crypto under an ariyah relationship?" No.
- We do not borrow the customer's crypto. The crypto stays in the customer's exchange account throughout.
- We do not have use rights. The customer retains exclusive control via the exchange's withdrawal flow.
- We have a read+spot-only API key — this is functionally a delegated-execution arrangement (closer to wakalah, agency) than a loan of any kind.
So the structural framing of HalalCrypto's service is:
- Ijarah (paid service for software + screening)
- Wakalah (limited agency to execute trades within pre-defined parameters)
Not ariyah, not qard, not mudarabah, not wadiah. Each contract type has different obligations; getting the framing right matters for both Shariah analysis and regulatory clarity.
