Wise charges an explicit service fee and shows the exchange rate it applies before you confirm. On the structural question, the majority scholarly view reported in Islamic-finance commentary is that a clearly disclosed charge for a currency-conversion service is permissible, and that the transparency of the disclosure is the material point. Note a separate question often confused with this one: screening bodies such as Musaffa and Muslim Xchange have assessed Wise plc as a stock as not Shariah-compliant for investment. That is a judgement about owning shares in the company, not about using it to send money.

Remitly quotes a fee and rate before you confirm the transfer. It is widely used across Muslim communities for family remittances and is generally treated in Islamic-finance commentary as a permissible service transfer on the same reasoning as other fee-charging operators. We have not located a specific formal ruling addressing Remitly by name.

Charges a service fee plus an exchange-rate margin. The same general reasoning applies as for other fee-based operators: the transfer itself is a service, not a loan at interest. The recurring scholarly caution concerns transparency — an undisclosed or poorly disclosed margin is the part commentators raise concerns about, rather than the existence of a margin as such.

Several Gulf Islamic banks offer remittance services governed by their own Shariah supervisory boards. For senders who want institutional oversight rather than a general scholarly view, this is the category to look at. Products and their certification differ by bank — verify the specific product with the bank's own Shariah board documentation rather than assuming it follows from the bank's name.
