Anti-Arab prejudice is ethnic while anti-Muslim prejudice is religious

Evidence

It is important to note that “anti-Arab” and “anti-Muslim” are terms that must not be conflated, although they frequently overlap: the former refers primarily to an ethnic identity, the latter to a religious identity. On the (rather controversial) distinction between anti-Semitism and anti-Judaism, see Gavin Langmuir, Toward a Definition of Antisemitism (Berkeley and Los Angeles: University of California Press, 1990), 57–62. — Ivan Davidson Kalmar, Derek Penslar, Orientalism and the Jews, 866
