Every Muslim must perform duties called the five pillars of Islam. These special acts are the basic principles of Islam. Some like prayers are required daily, while others may only need to be done once. Making a pilgrimage to Mecca at least once in Muslim?s lifetime is one of these obligations. Others include fasting and charity. For complete information on the five pillars of Islam, go to
