The fourth of the five principles of Islam is to fast every day in the blessed month of Ramadân. The fast became fard on the tenth day of the month of Sha’bân eighteen months after the Hegira and a month before the Ghazâ (Holy War) of Bedr. Ramadân means to burn. Sins of those who fast and beg Allâhu ta’âlâ for forgiveness in this month, will burn and perish.
It is written in the book Riyâd-un-nâsihîn that Hadrat Abû Hureyra ‘radiy-Allâhu ’anh’ stated in the book Bukhârî: Rasûlullah ’sall-Allâhu alaihi wa sallam’ declared, “When the month of Ramadân comes the gates of Paradise are opened and the gates of Hell are closed, and the devils are tied.”
