What traditions and beliefs did islam emerge from

Islam, like Christianity, Judaism and other world religions, varies in its  interpretations, rituals and practices. It is true that Muslims share certain fundamental beliefs, such as those expressed in the shahadah, the profession of faith: there is only one God and that Muhammad is His Prophet to whom was revealed the Qur’an. Yet, as the religion evolved after Muhammad’s death and spread beyond Arabia into many different regions and cultures, ranging from Bosnia and China to Yemen and Zanzibar, it came to be interpreted in diverse ways. This diversity was the result of the core set of religious beliefs interacting in complex ways with the many different contexts in which Muslims lived. Each of these contexts is defined by multiple factors, including its history, cultural traditions, its social, economic, political structures, and its geography and physical location in the world.

everything about this just does not make sense. what is the question?
