Millions of Muslims across Iran are celebrating Eid ul-Adha, which marks the culmination of the annual Hajj pilgrimage.
During the religious festival, Muslims slaughter livestock and distribute meat among friends, family and the poor.
The holiday commemorates Prophet Ibrahim or Abraham (PBUH)’s submission to divine order to sacrifice his son, Ismail (PBUH). However, God provided Ibrahim (PBUH) with a lamb to sacrifice instead.
Millions of Muslims around the world celebrate the auspicious occasion and gather in congregations in the early morning for Eid ul-Adha prayers.
The major rituals of the Hajj are performed during a five-day period from the 8th through the 12th of Dhu al-Hijjah in the Muslim lunar calendar.
The Hajj pilgrimage is a religious ritual, which must be performed by every able-bodied Muslim who can afford it at least once in his or her lifetime.
