I agree with what you said except this that Muhammad is an avatar of Lord Krishna.
In prati Sarga part 3, of Bhavishya Purana, Muhammad has been profesized and has been called an avatar of Tripurasura, a demon. If you want more details, I can provide them.
bansal is right the bhavishya puran talks about a demon Mahamad who is an avatar of Tripurasura. i dont know if we can relate that Mahamad with muhammad or not but on the web if you search for this, you will mostly find mis-translation and misinterpretation of zakir naik, that's all.
@madhuri: i dont know what you mean by "As was Jesus." but yes bhavishya purana also talks about a saint Ishua. he has been described as having saintly characteristics. and many people relate this Ishua with Jesus.
