Muslim identity is primarily defined by the adherence to the faith of Islam, which is based on the teachings of the Quran and the practices of the Prophet Muhammad. Muslims believe in the oneness of God (Allah) and follow the Five Pillars of Islam, which include faith, prayer, charity, fasting, and pilgrimage. Cultural expressions of Muslim identity can vary widely across different regions, influenced by local traditions and customs. This diversity is reflected in various practices, languages, and interpretations of Islam, making the Muslim community a rich tapestry of beliefs and lifestyles while maintaining a shared core of faith.
