Islam originated in the 7th century AD with the prophet Muhammad, who received revelations from God (Allah) that were recorded in the Quran. The five pillars of Islam are the core beliefs and practices that include the shahadah (faith in one God and Muhammad as prophet), salah (prayer five times a day), zakat (charity), sawm (fasting during Ramadan), and hajj (pilgrimage to Mecca if possible). Within 100 years of Muhammad's death, Muslim conquests spread Islam across the Middle East, North Africa, and parts of Europe.
