The month of Ramadhan is that in which the Quran was revealed, a guidance to men and clear proofs of the guidance and the distinction; therefore whoever of you is present in the month, he shall fast therein, and whoever is sick or upon a journey, then (he shall fast) a (like) number of other days; Allah desires ease for you, and He does not desire for you difficulty, and (He desires) that you should complete the number and that you should exalt the greatness of Allah for His having guided you and that you may give thanks. 2:185
In ahadith the month is also known as “Rabi-ul-Qulub” meaning the month of spring for the hearts. During Spring the earth suddenly becomes soft and dormant seeds come to life and this miracle of creation becomes visible to the human being. In the month of Ramadhan; He softens the heart of our souls but it is up to us to make the heart blossom making it “Qalbul Mu’minur Rahmaan” (A heart of a believer of the Rahmaan).
In this month there is visible readiness, a different preparation, the heart is ready to accept something, and it is seeking guidance from Allah. Hence the Merciful has established the month of Ramadhan for the descent of the Qur’an.
