See the grand scale of the Hajj pilgrimage as 2 million Muslims expected in Mecca

Over 2 million Muslims will take part in this week's Hajj pilgrimage to the holy city of Mecca in Saudi Arabia, as one of the world's largest religious gatherings returns to full capacity following years of coronavirus restrictions.

The Hajj is one of the five pillars of Islam, and all Muslims are required to undertake it at least once in their lives if they are physically and financially able to do so. For the pilgrims, it is a profound spiritual experience that wipes away sins, brings them closer to God and highlights Muslim unity.

The pilgrimage draws Muslims from around the world to Mecca, in Saudi Arabia, where they walk in the footsteps of the Prophet Muhammad and retrace the journey of Ibrahim and Ismail, or Abraham and Ishmael as they are known in the Christian and Jewish traditions.

Muslims do not worship the Kaaba, a cube-shaped structure covered in a black, gold-embroidered cloth, but view it as their most sacred place and a powerful symbol of unity and monotheism. No matter where they are in the world, Muslims face toward the Kaaba during their daily prayers.

Photos from this year's pilgrimage highlight the scale and impact of the Hajj.
