The five pillars are:
Testifying that there is no diety worthy of worship but Allah Alone, and that Muhammad is the Messenger of Allah, performing Salah (prayer), observing Siyaam (fasting), paying Zakat (alms), and performing Hajj (going to pilgrimage) for those who can afford.
These five pillars are called the pillars of Islam.
