Tiny little mistery

Hello Experts!

Got this coin in a lot together with some islamic olds.

11.5mm to 12mm

0.38g

Not even sure if is written something, looks like some kufik script

Any ideas?

Thank you for any comment

Isn't it similar to the tiny fals you helped me with at the beginning of the year?

I guess mine is much more light and tiny, and there are no fals abbasid or umayyad that small. 

Thank you by your comment, I asked on Zeno now, wil check if they could help me there.
