The Messenger of God (pbuh) said:
"Remember often the Ender of Pleasures"
When he (saw) was asked who the intelligent were he replied:
"Those who remember death most often, and prepare for it best.
They are the intelligent ones, who have gained
the honour of this world and a noble rank in the Hereafter."
And he (saw) said:
"Death is the most imminent of all hidden things lying in wait."
Now, if death is the nearest of the hidden things lying in wait,
then one must prepare for it through being decisive and taking
the greatest precautions in every condition in which it may come.
And this could be any time and under any circumstance.
