What are the five pillars of Islam that the Prophet Muhammad (saw) taught us?
      Narrated Ibn 'Umar:                          Allah's Apostle said: Islam is based on (the following) five      (principles):     1. To testify that none has the right to be worshipped but Allah and      Muhammad is Allah's Apostle.     2. To offer the (compulsory congregational) prayers dutifully and      perfectly.     3. To pay Zakat (i.e. obligatory charity) .     4. To perform Hajj. (i.e. Pilgrimage to Mecca)     5. To observe fast during the month of Ramadan.
