The ceremony was attended by head and cultural deputy of the Islamic Culture and Relations Organization (ICRO), director of the exhibition Hojat-ol-Islam Mohammad Reza Heshmati, and a number of foreign guests and ambassadors of Muslim countries in Iran.
It began with recitation of verses from the Holy Quran by internationally acclaimed Iranian Qari Mohammad Reza Pourzargari, which was followed by several speeches.
In his address, ICRO chief Abuzar Ebrahimi Torkaman referred to the influence of the Holy Book in the life of Iranians and said the influence of the Quran can be found in the literature, culture, arts, traditions and thoughts of Iranians.
"We should thank God that, with the blessings of the Quran, we live in a Quranic country," he added.
