How much is Islamic dollar in USD?

I'm curious, could you please clarify for me what exactly is meant by an "Islamic dollar"? Is this a reference to a specific type of currency used within Islamic economies or perhaps a digital currency that adheres to Islamic principles? As far as I'm aware, there isn't a universally recognized "Islamic dollar," so understanding the context of this question is crucial. That being said, if you're referring to a currency exchange rate between a hypothetical Islamic-based currency and the US dollar, the exact value would depend on a multitude of factors, including the economic stability and demand for both currencies. Could you provide any additional information or context that might help me give a more accurate answer?
