Pilgrims began gathering at the plain of Arafat on Tuesday to perform the most significant rite of the Hajj pilgrimage [1].

This gathering represents the spiritual pinnacle of the Hajj. The act of standing at Arafat is a mandatory pillar of the pilgrimage, without which the Hajj is not considered complete in the Islamic faith [1], [2].

Crowds of pilgrims, dressed in white ihram clothing, started arriving at the site at dawn on Tuesday, May 26 [3], [4]. The date corresponds to nine Dhu al-Hijjah 1447 in the Islamic lunar calendar [5].

Located near Mecca in Saudi Arabia, the plain of Arafat serves as the focal point for millions of worshippers who gather for prayer and reflection [1], [6].

"Crowds of pilgrims began arriving at the pure plain of Arafat with the dawn of Tuesday to perform the greatest pillar of Hajj," Youm7 said [3].

Other reports said that the pilgrims arrived at the site wearing their white garments of ihram [4]. This uniform dress symbolizes equality, and purity among the believers as they gather at the mountain [1], [4].

The event is part of a sequence of rituals that define the annual pilgrimage, drawing Muslims from across the globe to the Hejaz region of Saudi Arabia [1], [6].

“The act of standing at Arafat is a mandatory pillar of the pilgrimage”

The gathering at Arafat is the central theological event of the Hajj. Because the pilgrimage is invalid without this specific act, the logistical management of millions of people moving into a single plain creates one of the world's most significant annual challenges in crowd control and public health for the Saudi government.
