If I bought gold worth a thousand dinars and then sold it for a thousand and a half as long as the gold is of the same kind as cash, then the thousand must remain a thousand; because it is not permissible for me to sell the thousand dinars after a while for a thousand and a half. How is the crafted gold (jewelry) treated like cash or pure gold? Is it sold and bought as jewelry? Is zakat obligatory on jewelry? If it is of the same kind as cash, then zakat must be obligatory on it. Why then is gold sold at one price and bought at a lower price at the same moment? Isn't gold the same? Ibn Taymiyyah and Ibn Qayyim have detailed discussions on this, and they lean towards the permissibility of selling crafted gold on credit. Al-Qaradawi discussed this in his book 'Fiqh al-Zakat' and chose the opinion of Ibn Taymiyyah. The discussion is not about the hadiths of equality and immediate exchange in the session, but rather about treating crafted gold 'jewelry' as the same kind as cash.
