The Wisdom in poetry of Omar Khayyam

Omar Khayyam's Letter to Prophet Mohammed:
From me to Mustafa (Mohammed) please
receive my salaam (greeting of peace)

With complete honor, meanwhile tell him

Oh most respected one of the Hashemite tribe, why the bitter
drink(salty yogurt drink common in persia) is halal (legal)
in sharia (islamic law) while pure wine is haram (illegal)?

Prophet Mohammed's letter back to Omar Khayyam:

From me to Khayyam please receive my salaam

And meanwhile tell him that Khayyam is
still yet raw (not developed as a man)

When did I say that wine is haram? but

to a mature one it is halal and to an immature one it is harram

i think i made some mistakes in the farsi text above

This is by no means the word of God according to Muslims, but Omar Khayyam wrote this imaginary letter/ poem in between the 11th and 12th centuries while living in the persian speaking area near the border of Iran and Afghanistan. In much of his poetry, he praises wine and often sarcastically questions why such a great thing could be banned in his religion. This guy was a great mathematician who calculated the number of days in the year to a extremely accurate amount, he was a great philosopher and questioned God and his faith, which I think is really a great thing, not blasphemy as some people would say.
