Help identifying early Islamic copper coin (possibly Umayyad fals) [resuelto]

Hello Numista community,

I would greatly appreciate your help in identifying this old copper coin I have recently found. Based on its inscriptions, I believe it might be an early Islamic fals, possibly from the Umayyad or Abbasid period.

Here are some details:

- Diameter: Approximately 1.5 cm
- Material: Appears to be copper or bronze
- Language: Arabic inscriptions
- Obverse (front): Seems to say "La ilaha illa Allah"
- Reverse (back): Unclear text, but also in Arabic script

I've attached photos of both sides of the coin for better clarity. If anyone could help identify the exact type, origin, historical period, or even give an estimate of its value, I’d be very thankful.

Any information is welcome. Thanks in advance for your time and expertise!

Best regards,  

Other side reads as Muhammad rasul allah. 

Standard legends found on countless coins but not possible for precise i.d so are low in value
