Bukhari

Hadith Commentary:
(1)
The lines that the Messenger of Allah (sallallahu alayhi wa sallam) drew are as follows:
(The illustration is present in the book, Volume 9, page 396.)
Through this parable, the Messenger of Allah (sallallahu alayhi wa sallam) explained that a person harbors vast and extensive desires that even extend beyond his lifespan. Suddenly, death arrives and puts an end to the person, leaving his hopes unfulfilled, and he passes away before achieving them.
Shaytan has also employed this tactic. Allah the Exalted says:
"Shaytan makes them promises and fills them with hopes. But Shaytan’s promises are nothing but deception." ()
(2)
As a person grows older, Shaytan continues to instill undue aspirations in his heart, which increases the person’s greed and long hopes.
In pursuit of such desires, he commits various kinds of sins, until death suddenly seizes him and cuts off the chain of his vast and extensive wishes.
(3)
In any case, the promises and hopes that Shaytan gives to mislead a person are all nothing but deceit and trickery.
In contrast, Allah the Exalted has promised Paradise to the believers; that promise is absolutely true, and who can be more truthful than Allah the Exalted? Allahumma adkhilna al-jannata al-firdaws al-a‘la (Ameen).

Explanation:
1:
The meaning is that the lifespan of the son of Adam is very short,
death is closer to him,
but his desires and aspirations are limitless.
Therefore, a person should keep in mind his brief life while living in this world,
and strive to earn as many good deeds as possible.

Benefits and Issues:
A person's appointed time (ajal) is much closer than his hopes, therefore, it is necessary to prepare for its arrival.
Becoming engrossed in the world and becoming heedless of the Hereafter is extreme foolishness.
