Is it permissible to buy gold from a jeweler and pay half the price later as a deferred debt?

It is not permissible to sell gold for gold, or for silver, or for cash, except hand-to-hand. If any part of the gold or the price is deferred, then that is usury (riba). The scholars of the Permanent Committee for Issuing Fatwas were asked about selling gold jewelry for a deferred price (cash), and they replied that it is not permissible; rather, it is forbidden, due to the presence of Riba Al-Nasi'ah (usury of delay in taking possession). However, if the purchase is made with goods such as cloth or food, then deferring the price is permissible. It is obligatory to repent from this forbidden transaction and to clarify its ruling to people.
