The document discusses replacing the US dollar as the world's main currency with the gold dinar, which is more stable. It proposes establishing the gold dinar as the main currency for Muslim countries initially. While the idea was proposed in 2000, it was not implemented due to lack of willpower and questions around the dinar's ability to solve economic issues. However, interest in the gold dinar as a universal currency is increasing again. The document concludes by stating the research aims to identify factors contributing to acceptance of the gold dinar as a currency for Muslims in Kuala Lumpur, such as its compliance with Sharia law, reliability, or performance.
