Islam had a lot of help from trading, in order to spread as quickley and far as it did. I think that trade was a tremendous help with the spread of Islam. This is because, everyone was coming to Mecca to trade because Mecca had a huge trade center. Mecca was also prosperous and very important at this time, so everyone came to Mecca for trade. With so many different people from different cultures, when they came to Mecca, which was now a Muslim community, they got to see how the Islamic culture did things, as well as cultural celebrations, perhaps. With all of this, I think that the traders admired their way of doing things and took the religion back to their city. All in all, the Islamic religion spread temendously with the help of trade.
