Islam and the Great Spread

As Muhammad began to spread his influence around Arabia, more and more people began to believe. Muhammad was a merchant by trade. Trade at the time would be a contributor to how religion would spread around from east to west. What appealed to people to convert to Islam was that Islam was a religion that made every man equal to one another. Not one man was greater than another. Another appealing factor was that there was no priest or a middle man to Islam. It was you and God and a peaceful relation between the two.
