Hajj is the annual Islamic pilgrimage to Mecca, the holiest city for Muslims. It is a mandatory religious duty for adult Muslims who are physically and financially capable of undertaking the journey. The Hajj occurs from the 8th to the 12th of Dhu al-Hijjah, the last month of the Islamic calendar, and is one of the Five Pillars of Islam.
The Hajj has its roots in the time of Prophet Ibrahim (Abraham) and his family. According to Islamic tradition, the Kaaba, a sacred building located in the center of the Great Mosque in Mecca, was built by Ibrahim and his son Isma'il as a house of worship dedicated to the one true God.
For Muslims, the Hajj is a demonstration of their submission to Allah and an opportunity to seek forgiveness and spiritual fulfillment. It is a time of unity, equality, and humility as pilgrims from all over the world come together to perform the same rituals.
