Thousands of pilgrims completed their circumambulation around the Kaaba, Islam's holiest site, in the city of Mecca, during the final days of Hajj rituals.

The Kaaba, a cube-shaped structure, is the focal point toward which Muslims face during their daily prayers from anywhere in the world.

On Saturday pilgrims in Mina performed the stoning the devil ritual for the second day, which commemorates Prophet Ibrahim’s rejection of Satan.

Sunday is the final day the stonings can be performed, after which pilgrims will perform the farewell Tawaf, circumambulating, or circling the Kaaba counterclockwise seven times.

The Hajj, one of the Five Pillars of Islam, is required at least once in a lifetime for all Muslims who are physically and financially able.

This year’s pilgrimage, attended by more than 1.8 million people, is unfolding under tight logistical planning and safety precautions designed to manage the intense heat and large crowds.
