"When the month of Ramadan arrives, the gates of Paradise are open and those of hell closed, while the 'chayatines' (demons) are chained" [Reported by Bukhari and Muslim]

{O you, the wrapped (in your clothes)! Get up (to pray), all night long, except for a small part; its half, or a little less; or a little more. And recite the Quran, slowly and clearly. We are going to reveal heavy (very important) words to you. Prayer at night is more effective and more conducive to recitation. During the day you have to go about long occupations. And remember the name of your Lord and devote yourself totally to Him. }
[Sura 73 - Verses 1 to 8]
