They could at least look right here on wikipedia to see what the flag looks like.

It doesn’t look like a flag, it doesn’t like anything particularly, just some Arabic words.
I shop regularly at a small Middle Eastern grocery, and there is lots of Arabic in it and on the outside, including fliers that people put up.
It’s all just squiggly gibberish.
The typical WalMart worker using Wiki? HAHAHAHAHAHA!
