Islam is a monotheistic faith founded in the 7th century CE in the Arabian Peninsula, based on the revelations received by the Prophet Muhammad, who is considered the final messenger of God (Allah). Central to Islam is the belief in the oneness of God and the teachings of the Qur'an, which serves as the holy scripture. The Five Pillars of Islam—faith (Shahada), prayer (Salah), almsgiving (Zakat), fasting (Sawm), and pilgrimage (Hajj)—outline the fundamental acts of worship and ethical conduct that guide a Muslim's life.
