Forty Hadiths On Ramadan
Hadith No. 16
Fasts of the Month of Ramadan
The Holy Prophet (peace be upon him and his progeny) said: The month of Ramadan is the month in which Allah, The Mighty, The Glorious, has made fasting obligatory upon you. So one, who fasts in this month in a state of belief and with the intention of recompense, shall become free of his sins just as he was on the day when his mother gave him birth.Tahdheeb al-Ahkam, vol. 4, pg. 152
