Pilgrimage to a holy site is a core principle of almost all faiths. The Kaaba, meaning cube in Arabic, is a square building elegantly draped in a silk and cotton veil. Located in Mecca, Saudi Arabia, it is the holiest shrine in Islam. In Islam, Muslims pray five times a day and after 624 CE, these prayers were directed towards Mecca and the Kaaba rather than Jerusalem; this direction—or qibla in Arabic—is marked in all mosques and enables the faithful to know in which direction they should pray. The Qur‘an established the direction of prayer. TheMuslimPath.com All Muslims aspire to undertake the hajj, or the annual pilgrimage, to the Kaaba once in their lives if they are able. Prayer five times a day and the hajj are two of the five pillars of Islam, the most fundamental principles of the faith.
