The Comforter [Parakletos(Greek)]

Musalems claims that Holy spirit told in Gospel is really Ahmad, i.e. Muhammad, Christians misunderstood and there by Christians are Wrong.  See and read the link and let you decide.

"Parakletos" -in Greek New Testament word for "Comforter", literally “called to one’s side, i.e., to one’s aid”
"Periklutos" -in Greek 'praised one', which is 'Ahmad' in Arabic.

The Comforter [Greek Parakletos] 

Musalems claims that "Periklutos" is the real word not "Parakletos", Christians corrupted the Bible. 
Test to prove is to Replace the similar sentences where "Parakletos" were used, with the claimed word "Periklutos". If the sentence fit this we can assume that "Periklutos" can be real word.
One of another example of Usage of Parakletos in NT,  

1 John 2:1 says: "...we have one who speaks to the Father in our defense - Jesus Christ the Righteous One."  Here, the Greek word 'Parakletos' is used, defined as 'one who speaks in our defense'.

Replace with praised one "Periklutos" then verse will be like "Praised one to the father in our defense - Jesus Christ the Righteous One." See the meaning has been lost, "our defense" was the tail for advocacy, but here verse thus become headless with tail.
  John Gilchrist :"Here, the context dictates an advocate (paraklete), not a 'praised one'.  Just as Christ is our advocate, so He promised to give us an advocate, or Comforter to be in us.  'Periklutos' could not fit here.  (From Gilchrist, "Is Muhammad Foretold in the Bible?", p29) 

Conclusion:
See, Muhammad was mentioned in no where in Holy Bible. With out corrupting the  words in Bible Musalems were not able, to provide a single proof for the sake of their prophet. The perfection of Bible authenticity proved again.
