Bai al-Urbun is a sale in which the buyer pays the seller a deposit: if the purchase is confirmed within the agreed period, the sum is credited towards the price; if the buyer withdraws, the seller keeps it as compensation for holding the asset.
A mechanism close to civil-law earnest money
The principle resembles a non-refundable holding deposit: the buyer reserves an asset by paying part of the price while remaining free to back out. The difference lies in the religious basis, which requires a genuine sale of a lawful and specified asset.
Why did the legal schools split over it?
The Hanafi, Maliki and Shafi'i schools largely rejected it, seeing a gain without counter-value and an uncertain condition. The Hanbali school accepted it, relying notably on a transaction reported under Caliph Umar for the purchase of a house in Mecca.
The International Fiqh Academy's position
The Islamic Fiqh Academy attached to the Organisation of Islamic Cooperation accepted Urbun provided the option period is fixed in advance. It excluded exchanges requiring immediate possession on both sides, such as gold, silver or currencies.
Fixed deadline and subject matter
Without a known deadline, the buyer could block the asset indefinitely, creating excessive gharar. The seller must also own what is sold: a deposit paid on goods the seller has not yet acquired makes the arrangement open to challenge.
How does it differ from Hamish Jiddiyyah?
In a Murabaha, the bank sometimes asks for a security deposit before buying the ordered asset. That deposit does not become the bank's: if the client withdraws, it keeps only its actual loss and returns the remainder, unlike Urbun.
Why the security deposit comes before the sale
Hamish Jiddiyyah arises at the promise stage, before the bank owns anything; no sale exists yet. Urbun accompanies a sale already concluded subject to an option, which is why the seller may keep the whole amount.
A permissible substitute for call options?
Some researchers compare Urbun to a call option: the deposit acts as a premium and the buyer's maximum loss is known. Yet a conventional option trades on its own, whereas the Urbun deposit stays tied to an actual sale of the asset.
Capital-protected funds and equity strategies
Islamic managers have built funds where most capital sits in compliant instruments while a small portion serves as Urbun deposits on shares. If prices rise, the purchase is confirmed; otherwise only the deposit is lost.
Can an Urbun right be transferred to a third party?
Most Sharia boards refuse to let the right to confirm the purchase be sold separately, since that would mean trading a bare right detached from the asset. This limit prevents a secondary options market like those on derivatives exchanges.
Uses in property and trade
Outside financial markets, Urbun is used to reserve a home, a vehicle or a batch of goods while the buyer arranges funding. The seller, who turns away other buyers in the meantime, is compensated if the sale falls through.
Risks for buyer and seller
The buyer may lose a sizeable deposit if financing collapses. The seller bears the risk that market prices rise during the period without being able to withdraw. A deposit proportionate to the price balances these two exposures.
Points to check in an Urbun contract
Check the exact length of the option, how the deposit is credited to the price, whether the seller owns the asset, and the written opinion of the provider's Sharia board, since permissibility depends on the school followed and the structure chosen.
