Peace Alexei,
Frankly, I don't care what those atheists say about Muhammed, they'd say great things for any religious leader.
I doubt they would openly say "Yeah, Muhammed wasn't that great"
That would cause a riot!
Here's some quotes for Jesus Christ.

Muhammed is certainly far from being the greatest of the world's prophets.
Moses was much greater the Muhammed, he saved his entire race from permanant bondage, he recieved God's revealed Word, the Torah.
He led the Israelites through the desert for 40 years and brought them to their promised land.
Buddha, Guru Nanak, and Zoroaster were also much greater than Muhammed; they were wise and peaceful teachers that taught a message of love and universal brotherhood.
Jesus Christ was truly the most purest and greatest man the has ever lived.
Jesus never has a wife or girlfriend,
He never led and army, or caused another man's death, or killed anyone.
Jesus Christ completely changed the face of the world through His sacrifice for us, and His radical teachings challenge all of us.
His radical love for our enemies and His other amazing teachings were certainly something Muhammed failed to live up to.
Muhammed could have learned alot from Jesus Christ.
What should you ask yourself? WWJD or WWMD?
Who would you rather model yourself after? Jesus or Muhammed?
