Pan-Arabism had nothing to do with Islam. The only connection
comes from a number of Arab Nationalist assertions from which
Pan-Arabism was based. In those documents, the "Arab" is identified
by language (Arabic), character (similar cultural norms and ideas),
and religion (Muslim). However, this does not mean that Pan-Arab
Nationalism has anything to do with Islam in a religious sense. It
is only using Islam as a marker of identity (like the Census
would).
