Hajj literally means to "set out for place". For Muslim, it is a pilgrimage to Kaaba (House of Allah) in Makah. It is the responsibility of every physically and financially able Muslim to perform this offering at least once in a lifetime. Hajj is performed on the 10th day of Thou al-Hijjah (the 12th and the final month of the Islamic calendar). Hajj is the symbol of unity among the Muslims. Millions of believers from all over the world participate in the ritual irrespective of their caste, color, creed or tradition. It tears down the difference of social status and brings all the Muslims on one platform. During this occasion, men only wear two unstitched clothes; one covers the lower part, and the other is wrapped around the shoulders. Women wear simple white dress and headscarf.
