Hajj pilgrims have arrived at the Mina site in Mecca to perform the Day of Tarwiyah and the stoning of the Jamrat al-Aqaba [1].
These rituals represent central pillars of the Hajj pilgrimage, requiring the coordinated movement of millions of people within a concentrated area. The process involves specific spiritual observances, including prayer and the symbolic stoning of the devil, which are essential for the completion of the pilgrimage.
The movement of pilgrims occurred between June 4 and June 6, 2025 [2]. During this period, worshippers gathered in Mina to spend the Day of Tarwiyah, a time dedicated to prayer and supplication [2]. Following this, pilgrims transitioned to the Day of Sacrifice, also known as the Day of Nahr, to perform the ritual of throwing pebbles at the largest jamrah, Jamrat al-Aqaba [4].
To accommodate the massive influx of people, the site of Mina is equipped with a vast infrastructure of temporary housing. There are more than 160,000 tents located within the Mina valley to provide shelter for the pilgrims [3]. This infrastructure is critical for managing the density of the crowd and ensuring that worshippers have a designated place to rest between the various stages of the pilgrimage.
Saudi authorities manage the flow of traffic and pedestrians to prevent overcrowding during these high-density events. The transition from the Day of Tarwiyah to the Day of Sacrifice requires precise timing and logistical coordination to ensure that the stoning rituals are performed safely [2].
The pilgrimage remains one of the largest annual human gatherings in the world. The logistical scale is reflected in the sheer number of tents and the strict scheduling of rituals across the holy sites in Mecca [3].

The successful execution of the rituals in Mina depends on the intersection of religious adherence and massive urban logistics. The use of over 160,000 tents highlights the scale of temporary infrastructure required to prevent disaster in one of the world's most densely populated temporary settlements, where crowd control is the primary safety concern.
