Islamic faith is based on five cardinal principles
1. To bear witness that there is no true deity save Allah and that Hadrat Muhammad (may the choicest blessings & peace of Allah be upon him) is His chosen servant and true Messenger.
2. To establish prayer five times a day.
3. To pay "Zakaat" (poor due).
4. To perform Hajj
5. To observe fasts during the holy month of Ramadaan.
