Hmmm...you may have a point. I’m have no idea what Muzzies think of gingers.
Let me do some checking...
There are Muzzies that do dye their beards red with henna when they have done the Hajj.
“Red hair among Muslims is the most preferred color for hair. It is reported that Prophet Mohammed use to dye his hair red using Henna. Henna or Hina is a flowering plant which traditionally has been used to dye hair Red.There are no side effects to this.”

It might not be Muzzies doing this.
Ramses the Great dyed his hair with henna but that must have been because it was turning gray. His original color was red.
