Once a year, large numbers of Muslim pilgrims converging on Saudi Arabia unite in religious rituals and acts of worship as they perform the Hajj, one of the pillars of Islam. They fulfill a religious obligation, immersing themselves in what can be a spiritual experience of a lifetime for them and a chance to seek God’s forgiveness and the erasure of past sins.
Here’s a look at the pilgrimage and its significance to Muslims.
What is the Hajj?
The Hajj is the annual Islamic pilgrimage to Makkah in Saudi Arabia and involves a series of religious rituals. It’s required once in a lifetime of every Muslim who can afford it and is physically able to make it. Some Muslims make the journey more than once.
It is also one of the Five Pillars of Islam, in addition to the profession of faith, prayer, almsgiving, and fasting.
When is the Hajj?
The Hajj occurs once a year during the lunar month of Dhul-Hijja, the 12th and final month of the Islamic calendar year. This year, the Hajj will start on June 4.
When the Hajj falls during the summer months, the intense heat can be especially challenging. Amid extremely high temperatures last year, more than 1,300 people died during the Hajj, Saudi authorities announced then. The country’s health minister said at the time that the vast majority of the fatalities were unauthorized pilgrims who walked long distances under the sun.

What's the significance of the Hajj to Muslims?
For pilgrims, performing the Hajj fulfills a religious obligation and is also a deeply spiritual experience. It’s seen as a chance to seek God’s forgiveness for past sins, to grow closer to God and to walk in the footsteps of prophets.
Communally, the Hajj unites Muslims of diverse races, ethnicities, languages, and economic classes from around the world in performing religious rituals and acts of worshipping God at the same time and place. This leaves many feeling a sense of unity, connection, humility, and equality. Pilgrims also show up with their own personal appeals, wishes and experiences.
Many pilgrims bring with them prayer requests from family and friends that they would like to be said on their behalf.
Some spend years hoping and praying to one day perform the Hajj, or save up money and wait for a permit to embark on the trip.
Ahead of the journey, preparations may include packing various essentials for the physically demanding trip, seeking tips from those who’ve performed the pilgrimage before, attending lectures or consulting other educational material on how to properly perform a series of Hajj rituals as well as spiritually preparing oneself.

What are some of the rituals that pilgrims perform?
Pilgrims make the intention to perform the Hajj, and they enter a state of “ihram.” Being in ihram includes abiding by certain rules and prohibitions. For instance, men are not to wear regular sewn or stitched clothes that encircle the body, such as shirts, during ihram. Instead, there are simple ihram cloth garments for men; scholars say the purpose is to discard luxuries and vanity, shed worldly status symbols and immerse the pilgrim in humility and devotion to God.
A spiritual highlight of the Hajj for many is standing on the plain of Arafat, where pilgrims praise God, plead for forgiveness and make supplications. Many raise their hands in worship with tears streaming down their faces.
Other rituals include performing “tawaf,” circumambulating, or circling the Kaaba in Makkah counterclockwise seven times. The Kaaba, a cube-shaped structure, is the focal point toward which Muslims face during their daily prayers from anywhere in the world.
Among other rituals, pilgrims also retrace the path of Hagar, or Hajjar, the wife of Prophet Ibrahim, who Muslims believe ran between two hills seven times searching for water for her son.
What is Eid Al-Adha?
Eid Al-Adha, or the “Feast of Sacrifice,” is the Islamic holiday that begins on the 10th day of the Islamic lunar month of Dhul-Hijja, during the Hajj.
A joyous occasion celebrated by Muslims around the world, Eid Al-Adha marks Ibrahim’s test of faith and his willingness to sacrifice his son as an act of submission to God. During the festive holiday, Muslims slaughter sheep or cattle and distribute some meat to poor people.

MAKKAH: Each year, the eyes of the world turn to Makkah, where millions of pilgrims from a range of nationalities, ethnicities and cultures gather in a remarkable spiritual gathering that symbolizes the unity of Islam.

In this vast diversity and sheer scale, the foremost challenge lies in managing the movement of crowds in a brief timeframe and a geographically constrained area encompassing the Grand Mosque and the Holy Sites.

Alhough Hajj is, at its core, an act of worship, safeguarding pilgrims and managing their movements requires meticulous planning, technical precision, and close coordination between security, health, service and technology organizations.

Preparations for this year’s season underscored Saudi Arabia’s ability to integrate advanced technologies, institutional expertise, and forward-thinking initiatives to successfully orchestrate one of the most complex logistical operations in the world.

The movement of crowds in Makkah and the Holy Sites is managed by a centralized, data-driven strategy that relies on real-time inputs from surveillance cameras, aerial monitoring and location-tracking applications.

This integrated approach allows authorities to respond effectively to emergencies, proactively reroute pedestrian flow, anticipate congestion points and guide pilgrims with precision, ensuring the seamless and dignified continuation of rituals at every stage.

Coordinating the movement of over 2 million pilgrims in such a densely concentrated setting is a remarkable global accomplishment by any standard.

Crowd management expert Akram Jan spoke to Arab News about the efforts that went into organizing the Hajj season.

“Coordinating the movement of over two million pilgrims in such a densely concentrated setting is a remarkable global accomplishment by any standard,” he said.

Saudi Arabia, he said, has become a global leader in crowd management, offering valuable insights for other countries.

Crowd control for the pilgrimage includes carefully calibrated timetables, which significantly reduce congestion and enhance overall safety.

He said that such crowd control is achievable only through high-level inter-agency coordination, intensive field team training, and the ability to respond swiftly to changing conditions on the ground.

Hotelier Mohammed Hakim spoke to Arab News about how the Kingdom’s Hajj and Umrah preparations have progressed over the years.

These changes have redefined the sector, shifting it from a seasonal service model to a comprehensive, year-round industry.

He said: “It is now evident that the experience of pilgrims extends far beyond the performance of rituals; it has evolved into a comprehensive, well-orchestrated journey that meets the highest standards of service and excellence.”

“We are now in the era of ‘Smart Hajj,’ where crowds are managed through applications, meals are distributed via digital platforms, and the quality of camps and accommodations is continuously monitored through real-time sensors and data analysis,” he added.

“Pilgrim satisfaction is measured from the moment they arrive in the Kingdom until their departure, all with an unprecedented level of digital transparency.

“We are entering a new era for Hajj and Umrah — one that transcends boundaries and is no longer confined to specific seasons. It is driven by a vision of continuous growth, institutional integration, and human empowerment, moving toward a values-driven economy rooted in a deep commitment to renewal and progress.”
