This is where they go wrong. They can't claim Jesus as a prophet, because to be a prophet means that you must speak the truth as delivered to the prophet by God. Jesus said, "I am the Way, Truth and The Life; No one comes to the Father except by me."
Satan has them try to co-opt our Lord in the minds of muslims in order to battle against Him by gaining converts. It will fail.
We already know the ending. We just have to perservere.
