The Ruling on Borrowing with Financial Securities with an Increase

Question:
He says: Honorable Shaykh, may Allah grant you success. Some people borrow financial securities and lend them out, stipulating repayment with an increase. They say that riba (usury or interest) is only in the six categories, and that paper currency is not included in that. Is it permissible to work with them? And what is the stronger position in this matter?

Answer:
This is not permissible. The majority of scholars hold that riba extends beyond the six categories to anything that shares their operative cause. Paper currency shares with gold and silver the quality of being currency and a measure of value for things. Gold and silver are forbidden in terms of riba because they are currency, and paper is currency like them, so it takes their ruling. It takes their ruling. Yes.

Question:
He says: Honorable Shaykh.

Answer:
They seek out the opinions that suit them, and they leave aside the things that go against their desires and wishes. Yes.
