Islam is the fastest growing world religion and has spread to Indonesia, Africa, Russia and China. Many Muslims have migrated to America, Britain and Australia but wherever they live they believe in the fundamental truths of Islam. To be a believing Muslim involves five major obligations, which are known as the 'Pillars of Faith'. They are: 1. Muslims must pray 5 times each day - at daybreak, at noon, in the middle of the afternoon, after sunset and in the early part of the night. 2. Muslims must declare their faith by saying 'There is no god except for the One God and Muhammad is the messenger of God.' 3. Muslims must give money and help to poor people. 4. Muslims must fast for a whole month every year (the feast of Ramadan) by not eating or drinking during the day. 5. Muslims must try, at least once during their lives, to go on a pilgrimage to the Sacred Mosque in Mecca. In addition to these duties Muslems must not drink wine, they must not eat pork and they must not gamble. For Muslims there are in fact rules about almost everything - eating, drinking, dressing, bathing, table-manners, relationships between men and women and so on. All these rules make up the sacred law of Islam, called Shari'a.
