Muslim worshippers took part in countrywide prayers in Iran on Wednesday morning on the festive occasion of Eid al-Adha, one of the most important festivals of the Islamic calendar.
Together with Eid al-Fitr, Eid al-Adha is one of Islam's holiest festivals celebrated around the world and an official holiday in the Muslim-majority countries.
In Tehran, the Eid prayers were held at the University of Tehran, led by Ayatollah Seyed Ahmad Khatami.
Many political and military officials were among the participants in the Eid prayers.
Eid al-Adha marks the willingness of Prophet Abraham (AS) to sacrifice his son Prophet Ismail (AS) on God’s command.
Muslims mark the holiday by sacrificing livestock. The meat is shared among family and friends and also donated to the poor.
World Muslims have marked the festival, which comes as the annual Hajj season in Saudi Arabia draws to a close.
