Hellfire preaching

Hell-fire preaching is a religious term that refers to preaching which calls attention to the final destiny of the impenitent, which usually focuses extremely on describing the painful torment in the Hereafter as a method to invite people to religion. There may be degrees of emphasis, and degrees of extent to which hell is emphasized in the khutbah (sermon or speech in Islam).
