The most common version of the Palestinian national anthem does not use that word at all. The words in both Arabic and English are found here:

and here:

http://david.national-anthems.net/ps'.htm

The English version reads:

My country , my country
My country, the land of my grand fathers
My country, my country
My country, my nation, the nation of eternity
With my determination, my fire and the volcano of my revenge
The longing of my blood to my land and home
I have climbed the mountains and fought the wars
I have conquered the impossible, and crossed the frontiers
My country, my country, the nation of eternity
With the resolve of the winds and the fire of the guns
And the determination of my nation in the land of struggle
Palestine is my home, Palestine is my fire, Palestine is my revenge and the land of eternal
My country, my country, the nation of eternity
I swear under the shade of the flag
To my land and nation, and the fire of pain
I will live as a guerrilla, I will go on as guerrilla, I will expire as guerrilla until I will be back
My country, my country, the nation of eternity

i foud this in a dictonary:
commando- commando warfare, but i think this little bit military
u can try :
self sacrifice تضحية النفس - مصالحها
self immolation تضحية بالنفس عن عمد
self devotion تضحية النفس
leaving "fedayeen" as is exist is found it in the same dictionary , also guerilla, guerilla warfare exist as shown by Mr fuad
