Currency Exchange
Currency Exchange (Sarf) — Rules of Money Exchange
📖 The Scene: The Money Changers' Market — Medina in the Prophet's Era ﷺ
A merchant comes to Abdullah ibn Umar at the market...
The Merchant: O Abu Abd ar-Rahman! I sell camels at al-Baqi', I sell in dinars and take dirhams, and I sell in dirhams and take dinars!
Ibn Umar (reflecting): No problem...
The Merchant (surprised): And what is the condition?
Ibn Umar: That you take them at today's rate, and provided you don't part with something remaining between you!
The man goes to confirm with the Messenger of Allah ﷺ...
The Prophet ﷺ: "No problem taking them at today's rate as long as you don't part with something remaining between you."
The Narrator: This was the fundamental rule of currency exchange: immediate taking of possession at the day's rate!
Definition of Currency Exchange (Sarf)
📜 Linguistic and Technical Meaning
Linguistically: As-Sarf means returning and converting, hence the exchange of dirhams means their conversion.
In legal terminology: The sale of money for money, whether of the same type or different types.
Types of Currency Exchange Contracts
Gold for gold, Riyal for riyal, Dollar for dollar
Gold for silver, Dollar for euro, Riyal for pound
Legitimacy of Currency Exchange
📜 The Proof from Sunnah
From 'Ubadah ibn as-Samit, the Messenger of Allah ﷺ said:
"Gold for gold, silver for silver... equal for equal, like for like, hand to hand. If these types differ, sell as you wish provided it is hand to hand."
— Narrated by Muslim
The Consensus
Scholars are unanimous on the permissibility of currency exchange with its legal conditions. It is a necessary transaction to facilitate trade between nations.
Conditions for Valid Currency Exchange
The Two Fundamental Conditions of Exchange
First Condition: Taking Possession
🤝 In the session
"Hand to hand"
Always required
For all exchanges
Second Condition: Equality
⚖️ If same type
"Equal for equal"
Required if same type
Not if different types
First Condition: Taking Possession in the Session
📜 Proof for Taking Possession
The Prophet ﷺ said: "Hand to hand."
— Narrated by Muslim
The Prophet ﷺ said: "Do not sell gold for gold except equal for equal, do not let one part exceed the other, and do not sell the absent for the present."
— Agreed Upon
📖 What Does Taking Possession Mean?
The exchange office employee: I want 500 dollars.
The customer (taking out the riyals): Here are 1875 riyals.
The employee (handing him the dollars): Here are 500 dollars.
✅ Valid possession — Both received before parting.
Another customer: I want 1000 dollars, but the riyals will arrive tomorrow!
The employee: Sorry, impossible. Delivery must be immediate!
❌ Delay is not permitted — This is riba an-nasi'ah.
Second Condition: Equality if the Type is Identical
📖 When is Equality Required?
Example ①: Riyal for riyal
- 100 riyals = 100 riyals ✅
- 100 riyals ≠ 95 riyals ❌ (riba al-fadl)
Example ②: Dollar for euro
- 100 dollars = 90 euros ✅ (surplus is allowed)
- Because the type is different!
Rules for Gold and Silver Exchange
Table of Precious Metals Exchange Rules
| Élément | Statut | Notes |
|---|---|---|
| Gold for gold — Equality required, Possession required | ⚡ Conditionnel | |
| Silver for silver — Equality required, Possession required | ⚡ Conditionnel | |
| Gold for silver — Equality not required, Possession required | ✅ Halal | Permissible hand to hand |
📖 At the Jeweler's
The Customer: I want to exchange 50 grams of 21 karat gold for 18 karat gold.
The Jeweler: Okay! I'll give you 55 grams of 18 karat for your 50.
⚠️ This is riba al-fadl! Gold for gold must be equal in weight, regardless of karat.
✅ The Correct Method:
- Sell the old gold for cash
- Buy the new gold for cash
Paper Currency and Its Ruling
Do Paper Currencies Have the Same Ruling as Gold and Silver?
📜 The Preponderant View
Paper currencies have the ruling of the two precious metals (gold and silver) regarding:
- The obligation of zakat
- The application of usury rules
- The obligation of taking possession in exchange
The Cause: Monetary value — paper currencies are a price for things, so they take the ruling of gold and silver.
Fiqh Council Decisions
📜 International Islamic Fiqh Council Decision
"Paper currencies are conventional currencies having the full characteristic of monetary value. They have the legal rulings established for gold and silver regarding usury, zakat, salam, and all their other rules."
Paper Currency = Legal Islamic Money
Gold and Silver
Original monetary value
Common Cause
Monetary value
Paper Currency

The Buyer: I don't have dollars, but I have riyals!
The Merchant: No problem, pay in riyals at today's rate!
✅ Permitted — provided payment is at the rate of the day of payment, not the rate of the day of agreement.
📜 The Prophetic Proof
Ibn Umar said: We used to sell camels in dinars and take dirhams, and in dirhams and take dinars.

📖 From the Righteous Predecessors: The Precision of the Companions
📖 At al-Baqi' Market — Medina
A merchant questions Ibn Umar...
The Merchant: O Abu Abd ar-Rahman, I sell in dinars and receive in dirhams!
Ibn Umar: How do you do it?
The Merchant: He buys from me for ten dinars, and gives me a hundred dirhams.
Ibn Umar (warning): Be careful about two things:
First: Take them at today's rate — not yesterday's or tomorrow's!
Second: Don't part with something remaining between you — nothing should remain owed to you!
The Merchant: I understand! Now and here, not later!
Ibn Umar (smiling): Excellent! This is how the Messenger of Allah ﷺ taught us.
🎯 Contemporary Cases: Is This Exchange Valid?
Case 1: Traditional Currency Exchange Office
❓ The Question
I went to the currency exchange office to convert 1000 dollars to riyals.
The employee gave me the riyals immediately and took the dollars.
Is this permitted?
The Answer:
✅ Permitted — This is a valid exchange because:
- Taking possession occurred in the session
- Both counter-values were delivered before parting
- Nothing was delayed
Case 2: International Bank Transfer
❓ The Question
I want to transfer money to my family in another country.
The bank takes the amount in riyals and deposits in their account in local currency.
Is this permitted?
The Answer:
✅ Permitted — provided that:
- The amount is deposited in the recipient's account immediately or the same business day
- Constructive possession (money entering the account) replaces physical possession
Case 3: Buying Cryptocurrency
❓ The Question
I bought Bitcoin through a trading platform.
I paid in riyals and received the Bitcoin in my digital wallet immediately.
Is this permitted?
The Answer:
⚠️ Subject of contemporary disagreement —
- If cryptocurrencies are considered money, immediate taking of possession is required (achieved here)
- But the status of cryptocurrencies themselves is a matter of major disagreement among contemporary scholars
- Some have permitted them, others have prohibited them
Case 4: Forex (Currency Trading)
❓ The Question
I opened an account on a Forex platform to trade currencies.
I buy and sell and make profits.
Is this lawful?
The Answer:
❌ Generally prohibited — due to several legal violations:
Islamic Violations in Traditional Forex
No possession
- •Trades often deferred or virtual
- •No real currency delivery
Financial Leverage
- •Disguised usurious loan from broker
- •Trade 100 times what you own!
Rollover Interest (Swap)
- •Explicit riba on open positions
- •Paid or received each night
Futures Contracts
- •Selling what you don't own
- •Buying without possession
Islamic alternative: platform without leverage or interest with immediate possession
The Legal Alternative: A true Islamic platform without leverage or interest with immediate taking of possession.
Case 5: Money Transfer (Western Union)
❓ The Question
I sent money via Western Union.
The sender pays in dollars and the recipient receives in local currency after a few days.
Is this permitted?
The Answer:
✅ Permitted — because it's a hawala (transfer), not a currency exchange!
| Currency Exchange | Hawala (Transfer) |
|---|---|
| Sale of money for money | Transfer of debt from one person to another |
| Taking possession required | Taking possession not required |
| Sale transaction | Mutual assistance transaction |
Hawala is legally permitted, and the exchange happens at the moment of receipt at the day's rate.
💡 Stop and Reflect
📜 A Magnificent Prophetic Statement
"Hand to hand" — The Prophet ﷺ
This simple statement carries a magnificent rule to protect the economy from manipulation and illusory speculation!
Reflect with me:
🔹 How many global economic crises are caused by credit transactions and futures contracts without real taking of possession?
🔹 When you transfer your money, do you make sure the recipient receives it immediately?
🔹 If the world followed the rule of "hand to hand" in financial transactions, what would the global economy look like?
Remember: Sharia protects wealth from loss and uncertainty before protecting profits!
