The five-day Hajj pilgrimage will see some 2 million Muslims embark on a series of rituals in the desert city of Mecca in Saudi Arabia. It starts on Monday and it's one of the five pillars of Islam. All Muslims are required to do it at least once if they are physically and financially able. For the pilgrims, it is a deeply moving religious experience that brings them closer to God and reaffirms Muslim unity. But it can also be grueling at times, with long walks, outdoor rituals held in scorching heat, and massive crowds. Pilgrims say items like wide-brimmed hats, cross-body bags, portable chairs and slip-on shoes are essential for making the most of the experience.
