In separate messages on Sunday, Rouhani extended his felicitations to the Muslim leaders and nations, noting that enhanced unity among Muslims could help overcome unilateralism practiced by hegemonic powers that are incriminated in global acts of terror.
He added that this unity can also pave the way for further promotion of peace and security in the region and the world as well as consolidation of justice and brotherhood among Muslim nations.
Muslims traditionally celebrate Eid al-Adha, one of the most important religious feasts, with the sacrifice of animals such as sheep, rams, goats and cattle.
The act commemorates Prophet Abraham’s (peace be upon him) submission to divine order to sacrifice his son, Ismail. However, God provided Prophet Abraham with a ram to sacrifice instead after he successfully passed the divine test.
Millions of Muslims around the world attend the day’s prayers. In Iran, people from different walks of life will go to mosques to participate in the day's special prayers. A mass prayer will be also held in the Iranian capital, Tehran.
