Allah says in the Quran:
'O you who believe! Fasting is prescribed for you, even as it was prescribed for those before you, that you may attain God-consciousness. (2:183)
"In the month of Ramadan, the Quran, a book of guidance with proofs of guidance distinguishing right from wrong, was revealed. Therefore, whoever of you is present in that month let him fast. But who is ill or on a journey shall fast a similar number of days later on. Allah desires your well-being, not your discomfort. He desires you to fast the whole month so that you may magnify Him and render thanks to Him for giving you His guidance." 2:185
Accordingly, the month of Ramadan is called the month of the Quran; therefore, Muslims have tradition of reciting Quran frequently in this month.
