They say a picture says a thousand words. Well this 1 graph made by dr. Bill Warner with data from Mohammed's personal autobiography is so mind blowing and so damning even the greatest islam apologists can't defend.

So to summarize the numbers in the graph:
Mohammed (as a preacher in Mecca) in 13 years: 150 people converted to islam
Mohammed (as a political/military commander in Medina) in 10 years: 100.000 people converted to islam
Here's a quote from Mohammed himself admitting it was jihad that made islam successful...
Bukhari :: Book 4 :: Volume 52 :: Hadith 220
Narrated Abu Huraira:
Allah's Apostle said, "I have been sent with the shortest expressions bearing the widest meanings, and I have been made victorious with terror (cast in the hearts of the enemy), and while I was sleeping, the keys of the treasures of the world were brought to me and put in my hand."
