Is it permissible for one of us to go to one of the currency exchange companies that do not deal in riba (usury or interest)?

The questioner : A questioner asks and says: Is it permissible for one of us, for example, to go to one of the currency exchange companies that do not deal in riba (usury or interest), and give them, for example, one hundred dirhams in exchange for a "check" in Egyptian pounds? And is it not supposed to be a hand-to-hand transaction at the bank, as stated in the hadith, given that currency exchange in Cairo will only be through an interest-based institution?

The Shaykh : There is no doubt, in our view all of us, as I think, that these paper currencies have no intrinsic value. A blank sheet of paper is better in terms of intrinsic value than a paper currency; because this blank sheet can be used by a person to write something on it. Rather, the value of these paper currencies is a conventional value, and it is based on the gold allocated to them, each country according to what it has allocated for its currencies in gold. Therefore, we must keep in mind this fact: that when we buy a paper currency with another like it, we are not buying something that has value with something else that has value in itself. Furthermore, neither of the two currencies is one of the ribawi (interest-bearing) items. In reality, we are buying gold with gold. Therefore, the answer to the question is: that this should be hand-to-hand, first, for the reason I mentioned just now, that this currency has no intrinsic value, but its value is based on the gold allocated to it. And it is not permissible to trade in these currencies except within the limits of the necessary exchange that a person must have, for the reason I mentioned that these currencies have no intrinsic value, but their value is conventional. Then, for what we see every day of the rise and fall in some paper currencies, especially if their source is some weak countries, dealing in these papers with these paper currencies becomes most like gambling.
Therefore, I see that the answer to the previous question is that this transfer is not permissible; because it should be hand-to-hand, considering that the original basis is gold. Indeed, it is not permissible to expand this exchange process, for what I mentioned just now.
