Interesting, can you prove your statement with facts or references?
If you are talking about the Jihadi/Mujahed statement. I don't know what a contemporary arab term for "holy warrior".
As it seems that Mujahed has been around for a very long term, but has gained popularity only in the 1880s.

"Arabic mujāhidīn, plural of mujāhid, literally, person who wages jihad"

However it is the correct arab term, while jihadist seems to be combination of the arab word "jihad" with an english ending.
Here the first use of the word Jihadist is reported to be in 1989.

The Problem is, that i can't read arabic. I guess etymologic dictonaries in english on arabic languages are not that common.
I can ask a Professor in University, next time when I attend a course at the oriental department, but that might take a while.
