Dought & clear, - Is it permissible to plan to do something in the future even though when death comes it cannot be put off?.

I wanted to ask whether it is wrong to plan something I mean that we
have to do this tommorrow or next month or next year? Though I
strongly believe that death may come any moment.
Praise be to Allaah.
There is nothing to prevent a person from making plans and estimating
what he will need in the future, and thinking of what he hopes to
achieve, or saying, 'I will do such-and-such tomorrow,' or next week,
or next year.' But when he does that he has to say 'in sha Allaah (if
Allaah wills).' Allaah says (interpretation of the meaning):
"And never say of anything, 'I shall do such and such thing tomorrow,'
except (with the saying): 'If Allaah will.'…"
[al-Kahf 18:23]
Everything that a person intends to do in the future, or resolves to
do, or hopes to achieve, is based on hope, and hope is what motivates
people to do things. But the believer strives in this world for the
sake of that which will benefit him in both his religion and his
worldly affairs. So he takes the means and puts his trust in Allaah,
and seeks His help, as the Prophet(peace and blessings of Allaah be
upon him) said:
"Strive to do that which will benefit you, and seek the help of Allaah."
And Allaah says (interpretation of the meaning):
"… So worship Him and put your trust in Him…"
[Hood 11:123]
The kaafir and the negligent person, on the other hand, depend on the
means and forget their Lord in Whose Hand is Sovereignty and nothing
happens except what He wills. If a man looks at the obstacles which
stand between him and what he hopes for, and he thinks too much about
death and other obstacles, he will stop making efforts and neglect his
own interests. Thus it is apparent that man cannot live this life
without some hope which will make him strive to pursue the things that
he wants to achieve. But the believer should not hope for too much or
feel too content with this world, or prefer its pleasures; rather he
should strive to make the Hereafter his goal, and work to do righteous
deeds which will bring him closer to his Lord, and seek the help of
His blessings to obey Him, so that he may attain happiness in this
world and in the Hereafter.
