DUBAI: Muslims celebrated the first day of Eid Al-Adha on Tuesday, which marks the closing parts of the Hajj pilgrimage. The massive crowds had spent the previous night camped out in Muzdalifah, having performed the most important of the Hajj rituals, visiting mount Arafat, where they believe the Prophet Muhammad gave his last sermon. They had also endured poor weather conditions, which ranged from the intense heat of the summer sun, rain and sandstorms. Millions of pilgrims gathered at Mount Arafat on Monday. (AFP) On Tuesday the 2.4 million pilgrims walked to a complex in Mina to throw pebbles at three columns. It is here that Muslims believe the devil tried to talk the Prophet Ibrahim out of submitting to God’s will. Muslims believe Ibrahims faith was tested when God commanded him to sacrifice his only son Ismail. The pilgrims perform the stoning ritual, where they gather at three pillars that represent the Devil. They throw three stones, each bringing them closer to God as they repent the Devil. The stoning ritual area is on a multi-level structure that surrounds the pillars with a walkway to and away the site to ensure the safety of the millions of pilgrims. #يحدث_الآن.. حجاج بيت الله الحرام يرمون #جمرة_العقبة.#العالم_في_قلب_المملكة#حج1439هـ#واسpic.twitter.com/LpZ5HESuff— واس (@spagov) August 21, 2018 The final days of Hajj coincide with the Eid al-Adha holiday, or "Feast of Sacrifice." They traditionally slaughter sheep for the three-day festival, a tribute to the Prophet Ibrahim’s sacrifice of a lamb after God spared Ishmael, his son. They will consume some of the meat and give the rest to poor people unable to buy food.
