Unknown, Islamic?

Can anyone help with this one? It is rather worn but an unusual shape:

Thanks in advance.

I've had a response back on this one. Someone thought it may be a Muwahhids square dirham.

"the Muwahhids, produced another oddity, a square dirham that lacked every type of identifying mark and bore nothing other than religious phrases (and just occasionally a mintname). These square coins became extremely popular and were copied by the neighboring Christians, the small Islamic state of Granada, and several states in Northern Africa including the Hafsids of Tunisia and the Marinids of Morocco."

or maybe a Spanish Christian square coin:
