A prolific man in American history. I would argue he stands toe to toe with Lincoln and FDR in historical significance. They aren't taking one of those weird all our feet are in this picture things either. It has been argued, with some relevance, that his writing about natural rights was influenced by the Qu'ran. I think that John Locke, David Hume, and Jean-Jacques Rousseau were the biggest contributors by proxy, but he certainly took many actions in his life that was more in line with Qu'ranic values than Biblical values. Actions like freeing various slaves (and pushing for legislation regarding abolition) and certain beliefs in charity and public trust that are far more Muslim in nature than Christian. I think it's safe to say that reading the Qu'ran influenced his writing of the Jeffersonian Bible. Revisionist Bibles are fascinating because they reveal a largely Muslim idea that Jesus was a prophet, but the Bible has failed to present his revealed word. I think that's the interesting thing about studying the Qu'ran. The oldest Qu'ran in existence is from 16 years after the Prophet Mohammed's (PBUH) death whereas liberal estimates of age of the Gospel of Mark (the oldest) dates it 60 years after his death. Given the life expectancy of Jesus's time there is no way an eyewitness wrote even the oldest gospel. Islam relies on written tradition and Christianity on the oral tradition which is the major source of misreading the bible as a historicism of any kind. Another thing of note was that the Prophet Mohammed (PBUH) was said, in a Hadith, to have met a monk when he was a boy and the monk taught him about Christianity and of course there are some interesting bits in there about the monk recognizing Mohammed's (PBUH) significance at a young age. Note: PBUH=peace be upon him As part of my classical training in Islam I was taught Muslims use this as a blessing. I am not a Muslim (thus far) but recognize it as a title.
