Hajj is the fifth pillar of Islam. It is a visit to Al-Ka'bah, the house of Allah in Makkah, once in a lifetime by those Muslims who can afford to make the journey. It is performed during the period from the 8th to 13th Dhu'l Hijjah, the twelfth month of the Islamic calendar.
Al-Ka'bah, known as Baitullah (house of Allah), is a cube-like one storey building which was built originally by Adam and later rebuilt by Prophet Ibrahim (Abraham) and his son Ismail (Ishmael). It is the first house ever built for the sole purpose of the worship of Allah. Allah has blessed this AlKa'bah. Muslims who can afford to make the journey and are physically fit come here every year from all over the world.
The occasion may rightly be called the Annual International Muslim Assembly. During Hajj, the Islamic brotherhood becomes particularly evident and can be experienced in a special way by everyone who takes part. Barriers of language, territory, colour and race disappear and the bond of faith is uppermost. Everyone has the same status in the house of Allah -the status of His servant.
