besides the spread of islam through arabia by prophets it spread through trade routes like the silk road and through conflicts of war. through the silk road traders and members of the early muslim faith were able to go to countries such as china and create mosques around 627 c. e. as men from the middle east came to china they would get married to these asian women, which led to a spreading of the faith and traditions of islam in multiplicities. the crusades in the 9th and 10th centuries encouraged the spread of islam through the invasions of latin christian soldiers and muslim soldiers into each other's lands. the whole conflict began on the premises of a holy land and which group of people owned these lands that led to these foes invading their respective lands. as the religion itself spread so did its implications of ritual, such as prayer.
