Millions of Muslim pilgrims gathered on Mount Arafat near Mecca on Tuesday, May 26, 2026, to perform collective prayers [1], [2], [5].

The Day of Arafah represents the most sacred ritual of the Hajj pilgrimage. It serves as the spiritual climax of the journey, where pilgrims seek forgiveness and perform intensive prayers [1], [2], [4].

Gatherings on the plains of Arafat occurred during the second day of Hajj [2], [5]. Reports on the total number of attendees vary. Some sources said more than 1.5 million people joined this year's Hajj [4], while other reports said more than 2.5 million pilgrims assembled on the plains [3].

Conditions on the mountain were challenging as temperatures approached 40 degrees Celsius [4]. Despite the heat, thousands of Muslims remained on the site to complete the required rites [3].

The assembly on Mount Arafat is a mandatory part of the pilgrimage. Pilgrims typically wear white ihram garments to symbolize equality, and purity before God as they engage in the day's rituals [1], [2].

Following the prayers at Arafat, the pilgrims will proceed to Mina to continue the remaining steps of the Hajj. The event remains one of the largest annual gatherings of people in the world [1], [4].

The Day of Arafah is the most sacred ritual of Hajj, marking the climax of the pilgrimage.

The gathering at Mount Arafat is the theological centerpiece of Hajj; missing this specific day prevents a pilgrim from completing the pilgrimage. The discrepancy in attendance numbers—ranging from 1.5 million to 2.5 million—highlights the logistical complexity of tracking movement in one of the world's most densely populated temporary events.
