Islam is a monotheistic religion centered around the belief in one supreme and incomparable God—Allah. It teaches that Muhammad is the final messenger of God, following a long line of prophets, including Adam, Noah, Abraham, Moses, and Jesus. As the world's second-largest religion and the fastest-growing faith, Islam emphasizes the oneness of God, His mercy, and His sovereignty over all creation. The religion is built upon the Five Pillars: faith (Shahada), prayer (Salah), charity (Zakat), fasting (Sawm), and pilgrimage (Hajj), which serve as fundamental acts of worship and devotion. Muslims believe that God has provided guidance to humanity through divine revelations, particularly the Quran, which is regarded as the literal word of God, as well as through the teachings of the Prophet Muhammad. Islam also stresses the importance of compassion, justice, and accountability, encouraging believers to lead righteous lives in accordance with God's will.
