I'm not sure what you mean by "19th century meaning", but Mohammad himself was pretty vicious in his hatred for the jewish people.
As the quran goes on and on, it get more and more hateful towards the jewish people.
See what he did to the jewish tribe (called the Banu Qurayza).
Every male of puberty and above was beheaded, and the women were sold into slavery or ransomed (to whom is unclear).
The year was around 625.
If thats not anti-semetism, then what it is?
The term "antisemitism" was coined in the 19th century. Some will claim that by heritage that arabs "can't" be antisemetic.
The original definition of the term made it clear that it referred to Jews.
