The Hajj, Explained: The 4,000-Year-Old Journey at the Heart of Islam
A five-day pilgrimage retraces the trials of Abraham, Hajar and Ishmael, and draws well over a million believers to Mecca every year. Here is what happens, and why it matters to people of every faith.
Every year, in the last month of the Islamic calendar, the city of Mecca fills with pilgrims dressed in plain white. They have come from every continent to perform the Hajj, one of the five pillars of Islam and a journey that every Muslim who is physically and financially able is asked to make at least once in a lifetime. For those watching from outside the faith, the scenes can be both moving and unfamiliar. This short explainer, and the video above, walk through what the pilgrimage is, where it comes from, and what each of its rites means.
Roots that reach back four thousand years
Although the rituals of the Hajj as Muslims perform them today were established in the time of the Prophet Muhammad, the pilgrimage itself has origins that reach back more than 4,000 years. It is built on the trials of the prophet Abraham: the test of his willingness to sacrifice his son Ishmael, and the test of leaving his wife Hajar and the infant Ishmael alone in the desert.
According to Islamic tradition, Hajar, desperate for water, ran between the nearby hills of Safa and Marwah seeking help. When the child Ishmael struck his heel on the ground, God caused a spring to burst forth. That spring was named the well of Zamzam, and it still flows to this day.
Abraham was then commanded to build a small stone structure around the well, the Kaaba, to mark a place of sacred gathering for all who believed in the one God. He made a pilgrimage to the site each year, and that yearly journey became the foundation of the Hajj.
The well of Zamzam, which tradition says sprang up beneath the feet of a thirsty child, still flows today.
The first Islamic pilgrimage
In the year 632, the Prophet Muhammad performed the first Islamic pilgrimage, laying out for his followers the rites of the Hajj as they are still observed. Nearly fourteen centuries later, pilgrims follow the same sequence of steps, over the same ground, in the same order.
Preparing body and spirit
The Hajj is a deeply spiritual undertaking that lasts five days. Pilgrims prepare themselves both spiritually and physically under strict rules: they pray, they put on simple white garments that erase every visible sign of wealth or rank, and they set aside phones and social media. The point is to arrive as an equal among equals, with nothing to distract from the purpose of the journey.
The rites, step by step
Circling the Kaaba
Pilgrims first circle the Kaaba seven times, counter-clockwise, in a rite known as tawaf. It is the image most people associate with the Hajj: a vast, slowly turning ring of white around the black-draped cube at the center of the Grand Mosque.
Walking between Safa and Marwah
Next, pilgrims walk seven times between the hills of Safa and Marwah, retracing Hajar’s desperate search for water for her son. In this rite the whole pilgrimage takes on a human scale: a mother, a child, and a moment of need answered.
The day at Arafat
Pilgrims then gather at Mount Arafat to pray for forgiveness and mercy. This day is considered the pinnacle of the Hajj; without it the pilgrimage is not complete.
Casting the pebbles
Pilgrims collect small pebbles for the next rite: throwing them at three stone pillars in Mina, a gesture that symbolizes the rejection of Satan’s temptations and, by extension, of the temptations each pilgrim faces in daily life.
The sacrifice
Pilgrims offer an animal sacrifice, typically a sheep, goat or cow, and the meat is distributed to the needy. The act commemorates Abraham’s willingness to sacrifice his son in obedience to God, and it coincides with Eid al-Adha, the Festival of Sacrifice celebrated by Muslims around the world.
A final circling
A last circumambulation of the Kaaba concludes the rites, and the pilgrim who completes them returns home with the honorific title of Hajji.
The plain white garments erase every sign of wealth or rank. The pilgrim arrives as an equal among equals.
A gathering of millions
Between 1.5 and 2.5 million pilgrims perform the Hajj each year. In 2026, the Saudi General Authority for Statistics recorded 1,707,301 pilgrims, the great majority of them arriving from outside Saudi Arabia. Few events on earth bring so many people, from so many countries and languages, to one place for a single shared purpose.
Why we share this
The International Multi-Faith Coalition exists to restore sacrosanctity to all houses of worship and to build respect for the religious beliefs of others. Understanding is where respect begins. A neighbor who knows what the Hajj means, and why a colleague might save for years to make the journey, is a neighbor better equipped to defend that colleague’s right to worship in peace. We offer this explainer in that spirit, with our thanks to the organizations whose reporting and footage informed it.
Our message: To restore sacrosanctity to all houses of worship. We are family. Respect the religious beliefs of others.
