     Fifth pilar of Islam is Hajj:

The pilgrimage to Makkah, is the fifth pillar and the most significant manifestation of Islamic faith and unity in the world. For those Muslims who are physically and financially able to make the journey to Makkah, the Hajj is a once in a lifetime duty that is the peak of their religious life. The Hajj is a remarkable spiritual gathering of over two million Muslims from all over the world to the holy city. In performing the Hajj, a pilgrim follows the order of ritual that the Prophet Muhammad performed during his last pilgrimage.

The five pillars of Islam define the basic identity of Muslims - their faith, beliefs and practices - and bind together a worldwide community of believers into a fellowship of shared values and concerns.
