Ramadan :is the Month of Revelation of the Holy Quran
Imam Reza (A.S.) has said: If one asks, "Why is it that the fasts were made obligatory exclusively in the month of Ramazan and not in the other months?" it would be said, "(this is) because the month of Ramazan is the month in which Allah, the Exalted, had revealed the Holy Quran."
