.....what Jesus preached in the New Testament.

Yeah. And what did Jesus do?

Now compare that to what Muhammad, peace be upon him, preached and did.

A fair comparison?
In a nutshell: Peace versus violence & mayhem.

"Peace versus violence & mayhem."

I don't see too many Christians cutting the Old Testament out of their Bibles and throwing it away.
Muslims also believe that Jesus was a prophet of G*d.
They follow His Word about as well as Christians have done over the last 2K years.
Looked at over the long term, I don't see too many religions in a position to be pointing fingers.
