The Five Pillars of Islam are:

• Faith in the one God.  Muslims are obliged to bear public witness to the idea that there is only one God and that Muhammad is the prophet of God.
• Prayer.  Muslims must pray five times a day at set times.
• Charity.  Muslims must give a certain percentage of their wealth to help those who are in need. 
• Fasting.  Muslims must fast and abstain from various activities during daylight hours during the month of Ramadan.
• Pilgrimage.  Every Muslim who is financially and physically able to do so must make a pilgrimage to Mecca at least once in their lifetime.
