The Five Pillars of Islam are fundamental practices in Islam, considered to be obligatory acts of worship for all Muslims. They are summarized in the hadith of Gabriel. The Sunni and Shia agree on the basic details of the performance and practice of these acts, but the Shia do not refer to them by the same name. They are: Muslim creed, prayer, charity to the poor, fasting in the month of Ramadan, and the pilgrimage to Mecca for those who are able.
