Looks like the signs contain Arabic of some sort (or Chinese because of the sun figure?)...I am pinging jveritas, FR’s wonderful language translator for his opinion on this.
It is using one of the extremely complex and very old artistic Arabic writing but I can for sure read the word “allah”I think the whole phrase read “œla illah ila allah” which means “there no god but allah”. Again this is not a common Arabic writing, it is highly convoluted and 99.9% of people who speak and write Arabic cannot figure it out.
