CONSTANT AWARENESS OF BEING PREPARED
It is a duty upon every sane person to be prepared for his departure (from this world), for one does not know when he will be served by his Lord’s commands (to take away his soul) nor does he know how long it is going to be before he will be summoned (for the Day of Judgment).
I have seen so many people enchanted by their youth. They have forgotten that their peers no longer exist, yet they are preoccupied with prolonged hopes (to stay alive).
