This is a picture of a Mezuzah which hangs in the office of Rabbi Landau in Bnei Brak. On the bottom is written, "this Mezuzah was written by an Arab." It just goes to show how important it is to make sure that you get your Mezuzah from a reliable source. The Jewish law mandates that Mezuzahs be written by a Jewish, Torah observant scribe who is thoroughly trained in the laws of writting a Mezuzah.
