The term 'Moslem Pilgrimage to Mecca' refers to the religious journey of Muslims known as Hadj or Hajj. This pilgrimage is one of the five pillars of Islam and is a mandatory religious duty for all able-bodied Muslims who can afford it. The pilgrimage takes place during the Islamic month of Dhu al-Hijjah and involves visiting the holy city of Mecca in Saudi Arabia. During the pilgrimage, Muslims perform a series of rituals including circling the Kaaba seven times, running between the hills of Safa and Marwah, and throwing stones at the pillars of Mina.
