Hadees on Ramzaan,Ramzan kareem ahadees

Holy Prophet Muhammad (peace be upon him and his progeny) said: The month of Ramazan 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.
