Bismillah. This is THE event of London 2012, far more important than a sporting event or a diamond jubilee. It is a unique & historic occasion when the Ka’bah, symbol of the centre of our hearts, has in a sense come to Central London.
The exhibition is brilliant. Go and see it, and take your families & friends (kids go free). A particular connection with the UK is the story of Thomas Cook as Hajj travel agent from 19th-century British India. A “Thomas Cook Hajj travel ticket to Mecca” and pilgrim guidebook are on display. Perhaps Thomas Cook should look into this again: the barakah (blessings) may save their ailing business.
Also worth seeing is the “Church of the Holy Sepulchre” temporary exhibit (on the right as you enter the museum). This includes a brief history of Jerusalem and some details about the Ottoman edict that split the church building amongst six different churches (sects).
Relatedly, you may wish to see “The Journey of Love,” Imam Ibn al-Qayyim’s poem about the Hajj, an extract from his Qasidah Mimiyyah, elsewhere on this blog.
