Major General Hossein Salami made the remark in an address to the closing ceremony of a Quran competition for IRGC personnel and family members.
The ceremony was held Friday at the holy shrine of Imam Reza (AS) in Mashhad, northeast Iran.
He said the Quran is a brilliant truth that guides people from darkness and ignorance to light and faith.
Major General Salami added that the IRGC should be the manifestation of the Quran and protect it.
The IRGC members should know the Quran well and act upon its teachings, the commander added.
More than 14,000 IRGC personnel and family members took part in the 11th edition of the competition, which was held in categories like Quran recitation, Quran memorization and Adhan (call to prayers).
The final round of the contest was held in Mashhad with the participation of 974 finalists.
