Hojjat al-Islam Ansari Kermani recalls that Imam Khomeini used to recite Quran from night until morning prayers. Imam also kept reciting the holy book even after performing his morning prayers.
He used to read the Holy Scripture at least for eight times during a day and finished recitation of the full scripture within a month.
