"First the Saturday people, then the Sunday people."

In a January 1976 article in Commentary, titled "The Return of Islam," Bernard Lewis wrote, "In the period immediately preceding the outbreak of the Six-Day War in 1967, an ominous phrase was sometimes heard, 'First the Saturday people, then the Sunday people.'"

Today, on many pro-Israel websites and blogs, there are claims that the phrase is common in Arab grafitti, or as a placard in street demonstrations. I am curious about whether these claims are correct, or whether they might be recycled versions of Lewis's statement about 1967.

If you have information about the subject, please supply it in the comments. (Or e-mail it to me from the e-mail link on www.davekopel.org, if you prefer.) Comments are open only for the purpose of information about the quote "First the Saturday people, then the Sunday people." If you have personally seen such graffiti, or know of sources which have seen such grafitti, please supply the information. Conversely, if you have actual knowledge that the phrase is rare or non-existent in the Arab areas (particularly, areas near Israel) about which you have first-hand knowledge, please supply that information.
