Narrated By 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 observe fast during the month of Ramadan 5. To perform Hajj. (i.e. Pilgrimage to Makah)
