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 “la 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.
Yikes...if it were me, that thing would definitely come down off the wall, LOL! Thanks jveritas...you are the greatest!
