In a new short video titled "Inside the Caliphate," released by ISIS' Al-Hayat Media Center, an American-accented narrator describes how ISIS has introduced a smaller unit of currency -- the bronze fals -- to add to their gold dinar and silver dirham.

ISIS has extensively promoted their own currency system, stressing that using the coins is necessary to break away from the capitalism of the kuffar, or disbelievers.

The video shows religious police in a grocery store lecturing residents on the ISIS currency while waving around forbidden U.S. dollar bills.

"Despite the fierce and relentless campaign being waged by the nations of kuffar against the ISIS," he says, ISIS "continues striving to carry out Allah's order and to wage war on the satanic monetary system."

The bronze fals is being rolled out, the narrator says, "to help facilitate smaller financial transactions in a Sharia manner," with ISIS' monetary committee setting the valuations: one dirham equals 100 fals.

"All goods and financial transactions must now be priced and conducted using the new currency. This includes everyday goods as well as contracts, wages and services, including services provided by the ISIS various departments. And wherever ISIS coins are available, it is forbidden to deal with the insidious bank notes that have no intrinsic value."

The video, showing a sign at a checkout in Arabic and English mandating the use of ISIS currency, declares that the implementation of the new currency policy will "make us among the forerunners in forbidding evil and enjoining that which is good."

ISIS announced its plans to mint its dinars in late 2014, in an effort to escape and triumph over the "satanic usury-based global economic system."
