Islamic coin identification [opgelost]

Hello, i wanna buy this coin but there is no identification on it. Can someone help me?

I have a similar one with a not definitive ID - the obverse is near identical but reverse is not like yours.
The seller is from São Paulo? I got mine at a fair there (it was cheap because it has no ID).

I recommend to look on Zeno (www.zeno.ru). Posting diameter here can help.
==============================================
Eu tenho uma bem parecida com essa sem identificação definitiva - a frente é quase idêntica mas o verso não tem nada a ver com a sua.
O vendedor é de São Paulo? Peguei a minha numa feira lá (era barata porque estava sem identificação).

Eu recomendo olhar no Zeno (www.zeno.ru). Postar o diâmetro aqui pode ajudar.


My coin for comparison // Minha moeda para comparação:

Yes, he is from São Paulo, but before buying I want to identify it.

Citeer: "Felipe Cardoso"​Yes, he is from São Paulo, but before buying I want to identify it.

Perhaps my coin is from the same seller?

Anyways, you may want to look on medieval sultanates in Iran / Iraq (around 800-1100 AD).
And don't forget to measure diameter, this helps a lot in narrowing down.
