crusades through allied territory

[Meisterdieb]

What happens if a crusade from an allied faction wants to pass through my muslim provinces to get to their goal?

Will they acquire recruits from my troops also?
Or will they just loot?

from my experience its always looting, kinda makes sense, i mean the crusades are a christian thing and muslims just dont follow the christian thing since they worship allah.
