Selling paper riyals for metal with an increase

The questioner:
Tell me, O Shaykh, may Allah reward you, is it permissible to sell twenty riyals and a quarter of ten riyals for ten, or ten for nine?

The Shaykh:
It is not permissible; because the Saudi riyal is one single type, whether it is paper or metal, it is the Saudi riyal, one single type, and equality is required in it. This is a matter in which there has been confusion, because some scholars issued a ruling of permissibility, especially over the phone; some scholars rushed over the phone and issued a ruling of permissibility. The Permanent Committee issued a ruling of prohibition, and the correct view is with the Permanent Committee, because this is one Saudi riyal, and there is no consideration for it being paper or being nickel, because this paper has no value, and this nickel has no value; rather, it is the monetary value that the state has recognized, so it is one single type. Yes. Yes. Yes, indeed.
