Also if you look at the gifts of the Holy Spirit, these do clearly not Match Mohammed's life, he was not kind, gentle etc etc. History doesn't show that about Mohammed. In the beginning it says in the Bible the Spirit of God moved on the Waters, there's some science behind this, but anyway ... If Mohammed was the Holy Spirit, this scripture ....
Genesis 1:2 - "...And the Spirit of God moved upon the face of the waters"
Would look like ...
"...And the Mohammed of God moved upon the face of the waters"
Or ...
"...And Mohammed moved upon the face of the waters"
Making Mohammed fit in with the scriptures just doesn't work. Its blasphemous to say Mohammed is the Holy Spirit. Jesus said to his discliples the Holy Spirit will come after a few DAYS ... ok? Days, not 600 years, to stop twisting the scriptures to fit your own ridiculous theory.
Conclusion:
Mohammed is NOT the Holy Spirit. He was Visited by an Evil Spirit, but he certainly is no Holy Spirit or THE Holy Spirit. He was Human for a start and did not move upon the face of the waters as Genesis states. He wasn't even born then. Period.
