Hajj, also known as the pilgrimage to Mecca, is considered to be one of the Five Pillars of Islam and is a sacred obligation for all able-bodied and financially capable Muslims who can afford it. It is a journey to the city of Mecca, which is located in Saudi Arabia, and takes place annually in the Islamic month of Dhu al-Hijjah. During the pilgrimage, Muslims gather in Mecca and perform a series of religious rituals, including the tawaf (circumambulation) around the Kaaba, standing at the plain of Arafat, and throwing pebbles at the pillars representing Satan. The Hajj is considered to be a deeply spiritual and significant experience for Muslims, and it is an opportunity for them to reaffirm their faith and to strengthen their relationship with God.
