The document describes the Hajj, the annual Muslim pilgrimage to Mecca. It explains that Muslims are expected to make the pilgrimage once in their lifetime. The rituals include circling the Kaaba seven times, running between the hills of Safa and Marwa, camping in Mina and throwing stones at pillars representing the devil, traveling to Mount Arafat, spending the night in Muzdalifah, shaving hair or sacrificing an animal, and returning to circle the Kaaba again before completing the pilgrimage.
