What is the Islamic pilgrimage to Mecca that every Muslim is expected to make at least once?

The Islamic pilgrimage to Mecca that every Muslim is expected to make at least once in their lifetime, if they are physically and financially able, is known as the Hajj. It is considered one of the Five Pillars of Islam, which are fundamental practices that form the foundation (Review) of Muslim life. This profound spiritual journey is a mandatory religious duty for capable Muslims, symbolizing their submission to Allah and their unity with fellow believers worldwide.

The Hajj takes place annually during the Islamic month of Dhul Hijjah, the twelfth month of the Islamic calendar, lasting approximately five to six days. Pilgrims from diverse backgrounds gather in Mecca, Saudi Arabia, the holiest city in Islam and the birthplace of Prophet Muhammad. Before beginning the rituals, pilgrims enter a state of spiritual purity called Ihram, often wearing simple white garments, which emphasizes equality among all before Allah, regardless of wealth or status.

During the Hajj, pilgrims perform a series of rites that commemorate events in the lives of Prophet Ibrahim (Abraham), his wife Hagar, and his son Ishmael. These rituals include circumambulating the Kaaba, the cuboid-shaped building at the center of the Grand Mosque, seven times (known as Tawaf). Pilgrims also walk briskly seven times between the hills of Safa and Marwa (Sa'i), and stand in vigil on the plains of Mount Arafat, which is considered the most important day of the Hajj, for prayer and repentance. The pilgrimage is seen as an opportunity for self-renewal, spiritual cleansing, and forgiveness of sins, offering a deep connection to Allah and the global Muslim community.
