Is it considered usury to take gold from a person with a promise that its price will be transferred later by another person, and what is the solution if this is usury and the man may not agree to return the gold?

The immediate exchange of the two counterparts at the contracting session and before parting is a condition for selling gold for money (exchange). If the exchange does not take place, the transaction is void, and the two counterparts must be returned. If returning the sale is not possible, the gold may be utilized, and one should seek Allah’s forgiveness and repent to Him. Some scholars are of the opinion that if gold is manufactured (jewelry), it ceases to be a currency and becomes a commodity, thus not requiring immediate possession of the price.
