Three truth about Ramadan

Allah said, "When the month of Ramadan starts, the gates of the heaven are opened and the gates of Hell are closed and the devils are chained." [Bukhari] ...

Narrated Abu Huraira(r.a): The Prophet said:"... whoever fasts during Ramadan out of sincere faith and hoping to attain Allah's rewards, then all his past sins will be forgiven." (Sahih Al-Bukhari).

"Ramadan is the (month) in which the Quran was sent down, as a guide to mankind and a clear guidance and judgment (so that mankind will distinguish from right and wrong).." (Q 2:183)

It is called the night of Power (i.e Laelat-ut Qadr) or the night of blessing (Laelat-ul mubarak). The deed in this night is better than the rewards of deeds of 1,000 months (about 83.3 years).
