Moha,
Looking striclty at what the Bible says as the marks of a false prophet fits the discription of Mohammed. 1John 4:1-3
Deut. 18:22
NIV "If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken. That prophet has spoken presumptuously. Do no be afraid of him."
Looking at verse :21 states the question how does one know if the words are spoken are not from God and 22 goes into the criteria. This alone makes Mohammed under Gods criteria and he does not there he is not a prophet.

"...were any of Muhammad's predictions verifiable within his own lifetime? Although Muhammad, on occasion, predicted the victory of Islam in the battles which were fought in Arabia, there are no other precise predictions which we know of which demonstrate that his authority came from God (the victory of a battle has a 50-50 chance of being correct, or not). In fact, this was a cause for concern even for Muhammad, who, numerous times in the Qur'an mentions the distrust by others of his inability to produce a miraculous sign which would substantiate his authority (see Suras 10:21, 13:7 & 13:27).
There is little evidence from our scriptures which show that Muhammad had authority to claim prophethood. He was not born into the line of Jacob, nor did he speak in the name of Yahweh, nor did his revelations conform to the message which preceded him, and his predictions were not verifiable.
What, then, must be our conclusion? In Matthew 24:24-25 we read "...false prophets will appear and perform great signs and miracles to deceive even the elect... See I have told you ahead of time." In Deuteronomy 18:19-22 we find an even stronger warning: If anyone does not listen to my words that the prophet speaks in my name, I myself will call him to account. But a prophet who presumes to speak in my name anything I have not commanded him to say, or a prophet who speaks in the name of other gods, must be put to death. You may say to yourselves, 'How can we know when a message has not been spoken by the Lord?' If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken. That prophet has spoken presumptuously. Do not be afraid of him. "
