The Reward For 100 Years of Fasting

Hadrat Sayyiduna Salman Farsi (Allah Be Pleased with Him) has narrated that the mercy for both the worlds, The Master of Makkah & Madina, The Noble Prophet (Peace & Blessings of Allah be Upon Him) said, "There is a day & a night in the month of Rajjab; If a Person fasts during the day & stands (for worship) in the night, it will be as if he has fasted for 100 years. This is the 27th Rajjab, This is the day on which the The Holy Prophet (Peace & Blessings of Allah be Upon Him) declared as a Prophet."
