In the Name of Allah, the Most Merciful,

the Most Compassionate

Praise be to Allah, and may His peace and blessings be upon Muhammad,

and upon his family and companions, and all those who follow him

Why the name 'Ramadan'?
Holy Prophet Muhammad (peace be upon him and his progeny) said:
"Surely, the month of Ramadan has been named so because 
it scorches away the sins." 
Kanz al-Ummal, H: 23688

Ramadan: The Name of God

Imam Sadiq (A.S.) has said: Say not, "This is Ramadan" and "Ramadan has 
departed" and "Ramadan has arrived" for surely, Ramadan is one of the 
names of Allah, The Mighty, the Glorious, who neither arrives nor departs. 
Surely, arrives and departs that, which is ephemeral, Instead say: 
"The month of Ramadan". Al-Kafi, 4, pg. 70

Ramadan: 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 Ramadan and not in the other months?" 
it would be said, "(this is) because the month of Ramadan is the month in 
which Allah, the Exalted, had revealed the Holy Quran." 
Bihar al-Anwar, vol. 18, pg. 190

Reward for Recitation of the Holy Quran during Ramadan

Imam Reza (A.S.) has said: "Someone who recites one verse from the Book of Allah, 
The Mighty, The Glorious, in the month of Ramadan, is like one who has recited 
the entire Holy Quran in the other months." 
Bihar al-Anwar, vol. 93, pg. 344
