Sending money abroad: what to know about the exchange?
A transfer abroad is really two things at once: paying for a service, and exchanging one currency for another. Jurists call the exchange *sarf* — trading money for money — and it carries its own widely reported conditions.
Why this matters in my religion
Money sent to a mother or a sibling abroad is not a cold transaction. It is family support, and it is written into a record that outlasts the transfer itself.
That is what makes a clean path worth insisting on. Exchange between people rests on consent and honesty, not one side quietly taking from the other. Wealth must not be consumed except through trade by mutual agreement (Qur'an 4:29).
The Sunnah sets out the base rule for exchanging currencies and precious metals. This is the hadith of Ubadah ibn al-Samit, recorded by Muslim. “Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, and salt by salt, like for like and equal for equal, payment being made hand to hand. If these classes differ, then sell as you wish if payment is made hand to hand” (Sahih Muslim 1587)
The words worth holding onto for a transfer sit at the end. When the two things exchanged differ in kind, the exchange must still happen hand to hand.
The idea, simply
Two operations, one screen
The first: moving the money. A company or bank takes your money here so it reaches your family there. That is real work with real responsibility, and its home in fiqh is agency and hire. The classical books also discuss this under *suftajah*, a payment order.
The second: exchanging the currency. Paying in one currency so your family receives another. This is *sarf*, the sale of money for money, and it carries conditions that a transfer fee alone does not.
Most people fold both into one word, "fees," and never notice where the currency exchange sits inside that number.
Sarf's widely reported conditions
Drawing on the hadith above, jurists widely report two conditions for exchanging currencies:
- Same currency, same currency — riyal for riyal, dollar for dollar: equal amount, and handover before the two sides part.
- Different currencies — riyal for a foreign currency: the amount can differ, but handover before parting is still required.
Most contemporary scholars treat paper and electronic currency the same way as gold and silver for this purpose. Every currency is counted as its own kind. Fiqh councils have written on this in detail.
One question contemporary scholars have studied closely is this. Does an entry in a bank account count as handover, the same as cash in hand? Their answers differ in detail, and it remains a live question for a specialist, not something to guess at.
Suftajah: an old name for a familiar problem
Classical jurists already knew a close relative of the wire transfer. It meant paying money in one place to be repaid in another, called *suftajah*.
Some permitted it, for the safety it gives against the risk of the road. Others held it back, seeing it as a loan that draws a benefit to the lender. This transfer question is genuinely old, not something apps invented.
What changes the answer
| Where in your transfer | The question it opens | The area it is examined under |
|---|---|---|
| What is actually deducted | A service fee, a currency spread, or both? | Hire, and *sarf* |
| When the currency is exchanged | At your payment, or at their receipt? | Handover in *sarf* |
| The rate you are given | Fixed now, or set days later? | *Gharar* and uncertainty |
| Money while it is in transit | Who owns it, and who bears its loss? | Agency, or a debt owed |
| A transfer in the same currency | No exchange at all, so what is the fee for? | Hire alone |
| A fee that grows with time | For more work, or for the delay itself? | Widely a form of riba on debts — the detail is asked |
| Payment now, delivery later | A deferred exchange, or a loan? | *Sarf* and lending |
| Gold bought in one country, delivered in another | When did handover actually occur? | *Sarf* and the sale of gold |
| An unlicensed transfer agent | What does your country's law require of you? | Fulfilling agreements and lawful process |
What this does not mean
- It does not mean every transfer involves a forbidden exchange. Moving money is a service with its own fee; *sarf* is a separate, additional question.
- It does not mean every difference in the rate is an unlawful increase. Differing currencies do not require equal amounts, only handover without delay.
- It does not mean a flat fee and a percentage rate are treated alike. That distinction is worth asking about, not assuming.
- It does not mean this page rules on any company or app. The answer follows the contract's clauses, not the provider's name.
- It does not mean your family's need removes the question. Need is presented to a mufti, not settled by yourself.
From life
A young man stood at a transfer screen at eleven at night. Three numbers sat in front of him: the amount to send, a visible fee, and an exchange rate in small print.
He did the arithmetic and found the true cost was larger than the fee alone. The gap sat in the rate, and he did not know what that gap was called in fiqh.
He typed four questions into his phone. When does the currency exchange actually happen? Who is responsible for the money while it travels? Is this rate fixed right now? What is different about sending in the same currency instead?
Then he closed the app, and left the transfer until morning. He carried his four questions to someone who could answer them properly.
What does this require of me?
- Separate three numbers on the receipt: the amount sent, the visible fee, and the exchange rate actually used.
- Compare that rate against the open market rate, so you can see where the real cost sits.
- Ask when the currency exchange happens, and when handover is complete. That is the central question in *sarf*.
- Check whether the transfer uses the same currency at both ends. If so, no exchange has occurred, and only the fee needs asking about.
- Keep the receipt, with its rate and date. A record settles a dispute and helps a mufti answer well.
- Avoid a rate that is not fixed at the time you agree to it.
- Ask about an unlicensed agent before you use one. The question has a legal side as well as a religious one.
- Present the actual product to a mufti. Search money and transactions for similar cases, and ask what you cannot find at ask a question.
When do I need to ask a scholar?
Ask when the rate is set some days after you pay, rather than fixed at the time.
Ask when you are buying gold in one country for delivery in another.
Ask when a fee grows the longer the transfer takes, or a penalty applies to delay.
Ask when you work as an intermediary for other people's transfers and take a cut.
Ask when your money sits in an account you do not own and nobody guarantees.
Ask when the money comes from mixed or uncertain earnings.
Ask when two people you trust for knowledge answer your case differently.
