The excellence of Ramadan and Fasting

 1) The Messenger of Allaah (sal-Allaahu ‘alayhe wa sallam) said:When (the month of) Ramadhaan enters, the doors of heavens are flung open and the doors of Hell are shut, and the Shayaateen are chained up in a narration it mentions:When (the month of) Ramadhaan arrives, the doors of Paradise are opened And in yet another narration, it mentions:……the doors of mercy are opened [A]

2) And in the transmission of at-Tirmidhee (it mentions):A caller would call out: “O you who want good, proceed, and O you who want evil, cease. Allaah frees people from the fire, and this is done every night until Ramadaan is over” [B]

3) And he (sal-Allaahu ‘alayhe wa sallam) said:The reward for) all the actions of the son of Aadam are multiplied (from anywhere between) ten times to seven hundred timesAnd Allaah (Subhaanahu wa Ta’aala) said in a hadeeth qudsee :…except for fasting, then it is for Me and I will give reward for it; He left off his desires and his food for My sake. For the fasting person there are two pleasures: his pleasure at the time of breaking his fast and his pleasure when he meets his Lord. And the smell emanating from the mouth of the one who is fasting is better in the Sight of Allaah than the smell of musk. [c]
