The president made the remark on Saturday while addressing a ceremony held to honor Quran servants.
He appreciated the efforts of Quran servants and said they have taken great strides for guiding the society.
The president noted that one of the blessings of the Islamic Revolution of Iran was the spread of acquaintance with the Quran in society.
Rouhani also said his government is proud to serve the servants of the Hoy Quran and Ahl-ul-Bayt (AS).
He further described the Quran as the book of light and guidance and the main source of unity in the Islamic Ummah.
He said wherever there is discord among Muslims, the reason behind it is getting distanced from the Quranic culture.
Elsewhere in his address, the Iranian chief executive slammed the Zionist regime's aggressions on the oppressed people of Palestine and the world's silence over Israeli atrocities.
The ceremony for honoring Quran servants was held at the International Holy Quran Exhibition, which is underway at Holy Defense Garden-Museum in Tehran until Wednesday, July 13.
