It is often observed from our righteous predecessors that they regularly took account of themselves lest they become negligent of the Hereafter and fall under divine retribution that will be weighed against mankind on the Day of Judgment. When a fire torch was once lit for Umar Ibn Al-Khattab; he felt angdeep anxiety at its burning heat; so he reprimanded himself; "How will you be patient if you encounter this O son of Al-Khattab!" He was of course; making a worldly parallel with the unparalleled Fire of the Afterlife.
