allah was the Bedouin moon god. The name was used by mohammod because it was familiar. His koran was a composite of christianity, hindu and arab religious beliefs and stories. He took what he liked from each religion. The hadath was his follow up, sort of the amendments to the original writings which was for interpretation. Other hadaths by other leaders followed and are still being written today.
The koran was written as a plan for conquest. The very name islam means to submit. The religion was used to get followers to obey through threats of eternal damnation. Other religions use the same tactics today only not for conquest. It's a practice that has been used for thousands of years.
The koran demands hatred of the Jews. Why? Because mohammod was handed his first major defeat at the hands of a Jewish community. He made sure that all Jews would be condemned throughout history for that. An example of hating all for the actions of a few. And it carries over to this day.
mohammod was a charlatan and a conman. He created a religion for his own personal gain. A religion that has grown because of others who saw the personal gain they could achieve through subjugation and conquest. What really keeps islam in check is the various sects that have formed over the years dividing it. A religion that teaches hate and says allah wants you to be the judge of matters and take action yourself can only lead to turmoil when sects oppose each other. A united islam would be a very dangerous thing to the whole world.
