Muslims are united across boundaries of geography and culture through their observance of five practices known as the Five Pillars, or the Pillars of Islam. The Five Pillars of Islam are the five obligations that every Muslim must satisfy in order to live a good and responsible life according to Islam. These include pledging one's faith (witnessing, the shahadah), ritual prayer (salat), charity to the poor (zakat), fasting during the month of Ramadan (sawm), and pilgrimage to the holy city of Mecca (hajj).
The Five Pillars are mentioned in the Quran, and are required of all Muslims. Sunni and Shi'i Muslims agree that these are the essential duties of all Muslims. Learn more about the Five Pillars of Islam and what they mean to Muslims.
