Hajj is the fifth Pillar of Islam and another form of worship. It is an annual pilgrimage to the holy sites in Mecca which each adult Muslim, who can afford it, has to perform once in a life time. Apart from the financial aspect, the ability to afford the pilgrimage also means that one is able to travel and perform the Hajj in peace. During Hajj, the person who intends to perform it is required to travel to Mecca during the prescribed days and observe all the rites and ceremonies. During Hajj, Muslims from all corners of the world gather in Mecca and perform the rites of Hajj and thus strengthen the bond of Muslim unity. Muslims perform Hajj in order to visit the holy sites where their faith started. More importantly it is a pilgrimage to the Ka'aba, which we believe is the first place of worship ever built on this earth, Muslims thus refer to it as House of God.
The ceremony of Hajj is also symbolic of the Unity of God; all Muslims gather from the four corners of the earth in one spot at an appointed time and worship God. There are no difficulties to perform Hajj apart from the obvious financial commitment in order to travel to Mecca.
