Hajj pilgrimage in Mecca

MECCA, SAUDI ARABIA - AUGUST 12: Muslim prospective Hajj pilgrims circumambulate the Kaaba at Masjid al-Haram in Mecca, Saudi Arabia on August 12, 2019 on the second day of Eid Al-Adha (Feast of Sacrifice) after stoning the Jamarat pillars that symbolize the devil as a part of the annual Islamic Hajj pilgrimage. Muslims worldwide celebrate Eid Al-Adha, to commemorate the holy Prophet Ibrahim's (Prophet Abraham) readiness to sacrifice his son as a sign of his obedience to God, during which they sacrifice permissible animals, generally goats, sheep, and cows. Eid-al Adha is one of two most important holidays in the Islamic calendar, with prayers and the ritual sacrifice of animals. (Photo by Halil Sagirkaya/Anadolu Agency via Getty Images)
