It is well known that there is a special relationship between the Mathnawi and the Koran. The bond between the two is most popularly epitomized in the lines that are affixed to the title pages of lithograph copies of the Mathnawi:
How can I describe that eminent personage?
Not a messenger is he yet he has a message
The spiritual Mathnawi of Mawlavi
Is the Qur’an expressed in Pahlavi.
