If all the stages through which a person will have to pass, death is the most certain. Everyone who is alive now will be dead sometime in the future. One day the eyes of those who see will fade and their tongues freeze into silence. Every human being will one day be leaving this world, never to return, and entering a world which he will never leave.
The gravity of the situation lies in death not being the end of life, but rather the beginning of a new, eternal life, a world of everlasting reward or retribution.
Everyone is on a journey from life to death. Some have set their sights on the world, others on the Hereafter.
Some strive to satisfy their own desires and egos; others are restless in love and fear of God. Both types of people appear to be the same in this world. But in relation to the life after death, there is a world of difference between the two: those who live in God and the Hereafter are redeeming themselves, while those who live in worldly pleasures and selfish desires are condemning themselves to doom.
Righteous people have a different attitude to death from the disobedient. They are concerned with what comes in the wake of death; they focus their attention on gaining an honourable position in the life after death. Those who disregard the existence of God and the Hereafter, on the other hand, are caught up in worldly affairs. Their ultimate ambition is worldly honour and prestige.
We are obsessed with the world, which meets our eyes. We fail to pay attention to the call of truth. If we were to see the next life with our worldly vision, we would immediately submit to God. We would realise that if we do not submit to Him today, we will have to do so in the future world when submission will profit no one.
