The ruling on sending money in one currency and receiving it in another, and whether hand-to-hand exchange is required?

Question:
May Allah reward you. He says: Honorable Shaykh, may Allah bless you, what is your view regarding someone who exchanges currency, meaning he receives an amount of riyals here and then hands it over to their representative in Sudan, for its equivalent in Sudanese pounds there? And is it permissible for a person to make this work a profession for earning a livelihood? And is hand-to-hand exchange required in such transfers?

Answer:
Yes, hand-to-hand exchange is required in the same session, because this is exchanging one currency for another. The Prophet (peace and blessings be upon him) commanded hand-to-hand exchange. So if one sells cash for cash, which is called currency exchange, or substitutes it, hand-to-hand exchange in the same session is necessary. Otherwise, this becomes riba al-nasi'ah (usury of deferment). What people are doing now is problematic, but the way out of it is to buy the currency he wants to send to his family here, then send it via banks or financial institutions, carrying it to that country to be delivered to the person it was sent to. The hand-to-hand exchange takes place in this country, and this currency is sent as a trust to the other country and delivered to the person it was sent to. Yes.
