Overview
Islam is an Abrahamic monotheistic religion founded by Prophet Muhammad in the 7th century in the Arabian Peninsula. The word 'Islam' means 'submission' or 'peace,' reflecting the religion's core concept of submitting to the will of God (Allah). With approximately 1.8 billion followers worldwide, Islam is the second-largest religion globally and the fastest-growing major faith tradition.
Core Beliefs
Islam's foundational beliefs center on monotheism: Muslims believe in one God (Allah) who is all-powerful, all-knowing, and merciful. Key Islamic beliefs include the existence of prophets who communicated God's message, the Day of Judgment when all people will be held accountable for their actions, and Paradise and Hell as eternal destinations based on one's deeds during life.

Sacred Texts and Teachings
The Quran, Islam's holiest scripture, comprises 114 chapters containing teachings believed by Muslims to be revelations from God to Prophet Muhammad. The Sunnah, the teachings and practices of Muhammad documented in Hadith collections, provides guidance on Islamic law and ethics. Together, these texts form the basis for Islamic jurisprudence (Sharia) and moral principles followed by Muslims.
Global Islamic Community
The Muslim community spans diverse cultures, nations, and ethnicities across the Middle East, North Africa, South Asia, Southeast Asia, Europe, and the Americas. While Islam is practiced among diverse groups with regional variations, Muslims share common core beliefs and practices. Major Islamic traditions include Sunni Islam (approximately 90% of Muslims) and Shia Islam (approximately 10%), with additional schools of thought reflecting different interpretations of Islamic law and practice.
