He is asking about time: is it created? Will it exist in Paradise? Will time cease to exist?

Praise
be to Allah

Firstly:

Allah, may He be
glorified and exalted, says (interpretation of the meaning):

“By
Al-‘Asr (the time).

Verily, man is in loss,

Except those who believe (in
Islamic Monotheism) and do righteous good deeds, and recommend one another
to the truth (i.e. order one another to perform all kinds of good deeds (Al-Ma‘roof)
which Allah has ordained, and abstain from all kinds of sins and evil deeds
(Al-Munkar) which Allah has forbidden), and recommend one another to
patience (for the sufferings, harms, and injuries which one may encounter in
Allah’s Cause during preaching His religion of Islamic Monotheism or Jihad)”

[al-‘Asr
103:1-3].

Ibn Katheer (may
Allah have mercy on him) said:

‘Asr means time
(zamaan) in which the deeds of the sons of Adam, good and bad, take place.
Maalik said, narrating from Zayd ibn Aslam, that ‘Asr means the afternoon,
but the first view is more well-known.

Tafseer Ibn Katheer (8/457).

Ibn ‘Uthaymeen
(may Allah have mercy on him) said:

“By
Al-‘Asr (the time)”.
It was said that what is meant is the end of the day, because the end of the
day is the best of it, and ‘Asr (afternoon) prayer is called as-salaah
al-wusta, i.e., the best prayer, as the Prophet (blessings and peace of
Allah be upon him) called it.

And it was said
that al-‘Asr is time (zamaan), which is the more correct view. Allah swore
by it because of what happens in it of changes in situations and alterations
of matters, and the changing fortunes of people, and other things that are
seen when present and spoken of when absent. Al-‘asr is the time (zamaan) in
which people live, with the vicissitudes of hardship and ease, war and
peace, health and sickness, good deeds and bad deeds, and other things that
are well-known to all people. Allah swears by it that “Verily,
man is in loss.”

End quote from
Tafseer al-‘Uthaymeen (p. 307)

What is meant by
time (zamaan) is the arena in which people’s deeds and actions take place.
In general, it is the duration of their life in this world.

Secondly:

This time
(zamaan) is something that Allah has created, because Allah, may He be
exalted, is the Creator of all things. He is the Creator of time and the
Creator of place.

Al-Bukhaari
(4826) and Muslim (2246) narrated that Abu Hurayrah (may Allah be pleased
with him) said: The Messenger of Allah (blessings and peace of Allah be upon
him) said: “The son of Adam offends Me. He inveighs against ad-dahr, but I
am ad-dahr, in My hand is control, I alternate the night and day.”

Shaykh al-Islam
Ibn Taymiyah (may Allah have mercy on him) said:

The words in the
hadith, “in My
hand is control, I alternate the night and day”
confirm that what is meant is not time (zamaan), because Allah tells us that
He alternates the night and day, and time (zamaan) is night and day. The
same hadith indicates that it is He who alternates and controls time, as is
indicated by the verse in which Allah, may He be exalted, says
(interpretation of the meaning):

“See
you not that Allah drives the clouds gently, then joins them together, then
makes them into a heap of layers, and you see the rain comes forth from
between them. And He sends down from the sky hail (like) mountains, (or
there are in the heaven mountains of hail from where He sends down hail),
and strike therewith whom He wills, and averts it from whom He wills. The
vivid flash of its (clouds) lightning nearly blinds the sight.

Allah causes the night and
the day to succeed each other (i.e. if the day is gone, the night comes, and
if the night is gone, the day comes, and so on). Truly, in these things is
indeed a lesson for those who have insight”

[an-Noor
24:43-44].

Allah, may He be
exalted, states in more than one place in the Quran that He created time,
such as the verses in which He says (interpretation of the meaning):

“and
originated the darkness and the light”

[al-An‘aam 6:1]

“And
He it is Who has created the night and the day, and the sun and the moon,
each in an orbit floating”

[al-Anbiya’
21:33].

And there are
other texts which clearly state that He is the creator of time (zamaan).

Thirdly:

There is no
place in this world in which there is no time; rather that cannot be
imagined, for time and place are bound together. Time is the duration of the
existence of this universe, and place is the space that is occupied by
created entities when they exist. If they stop occupying space, then this
means that they have ceased to exist and no longer exist. Similarly, if no
time passes for them, then they never existed in the first place.

Shaykh al-Islam
said:

No rational man
should ever think that Allah is time (zamaan), for time refers to the
measurement of movement, and the measurement of movement is a kind of
description that is connected to something else, such as movement and
stillness, black and white. No rational man can say that the Creator of the
universe is a kind of description that is connected to some essence or item,
for descriptions cannot be independent; rather they need something to be
connected to.

End quote from
Majmoo‘ al-Fataawa (2/492)

Events that
happen must have a time and place in which to occur, and no event can be
imagined without a time and place. These three are bound together.

Fourthly:

Time (zamaan)
will exist in paradise, but it cannot be compared to time in this world, as
Ibn ‘Abbaas (may Allah be pleased with him) said: Nothing in Paradise
resembles anything in this world except in name. According to another
version: Nothing in this world will exist in Paradise except the names of
things.

End quote from
Tafseer at-Tabari (1/392)

The same applies
to time (zamaan) and everything having to do with it in the hereafter: it
will be different from what it is in this world.

Shaykh al-Islam
(may Allah have mercy on him) said:

What exists in
the hereafter is not the same as what exists in this world, even though they
may be similar in some ways and the same names may refer to them.

End quote from
Majmoo‘ al-Fataawa (5/207).

Shaykh al-Islam
also said:

It is well-known
that Allah, may He be glorified and exalted, created the heavens and the
earth, and He originated darkness and light, then those who disbelieved held
others as equal with their Lord. Allah, may He be exalted, says
(interpretation of the meaning):

“Verily!
In the creation of the heavens and the earth, and in the alternation of
night and day, there are indeed signs for men of understanding”

[Aal ‘Imraan
3:190].

And there are
other, similar verses in the Quran. It is well-known that the day is
connected to the sun. As for the night, whether that refers to when there is
no light, or it refers to a transient condition as some people say, or it
refers to dark entities as others say, Allah has created all of that and He,
may He be glorified and exalted, is as ‘Abdullah ibn Mas‘ood said: There is
no night or day with your Lord; the light of the heavens is from the light
of His Countenance. In the verse (interpretation of the meaning),
“And
they will have therein their sustenance, morning and afternoon”
[Maryam 19:62],
there is an indication that the people of Paradise will know when it is
morning and afternoon by means of lights that will appear from the direction
of the Throne. At some times there will be more light than at other times,
for there will be no darkness there, and these lights are all created by
Allah, may He be exalted.

End quote from
Bayaan Talbees al-Jahamiyyah (2/284-286).

Ibn Katheer (may
Allah have mercy on him) said in his commentary on the verse
“And
they will have therein their sustenance, morning and afternoon”
[Maryam 19:62]:

That is similar
to our time of morning and afternoon. It does not mean that there will be
night and day there, but they will have times that come and go, and they
will recognise it by certain types of lights.

End quote from
Tafseer Ibn Katheer (5/218).

The people of
Paradise will not need to calculate time as people in this world do. Allah,
may He be exalted, created night and day, sun and moon, and He created time
calculations so that people may know when to perform acts of worship and to
keep track of interactions. But in paradise, they will not need any of that.

Fifthly:

Time (zamaan) in
this world will cease to exist, because what is connected to it will come to
an end. The movement of the sun and moon will also cease. Allah, may He be
exalted, says (interpretation of the meaning):

“Whatsoever
is on it (the earth) will perish.

And the Face of your Lord
full of Majesty and Honour will remain forever”

[ar-Rahmaan
55:26-27].

But time in the
hereafter will never cease to exist. Allah, may He be exalted, says of the
people of Paradise (interpretation of the meaning):

“But those who
believe (in the Oneness of Allah – Islamic Monotheism) and do deeds of
righteousness, We shall admit them to Gardens under which rivers flow
(Paradise), abiding therein forever”

[an-Nisa’ 4:57].

And Allah, may
He be exalted, says concerning the people of Hell (interpretation of the
meaning):

“Verily, those
who disbelieve and did wrong [by concealing the truth about Prophet Muhammad
(blessings and peace of Allah be upon him)and his message of true Islamic
Monotheism written in the Tauraat (Torah) and the Injeel (Gospel) with
them], Allah will not forgive them, nor will He guide them to any way, –

Except the way
of Hell, to dwell therein forever”

[an-Nisa’
4:168-169].

Al-Bukhaari
(4730) and Muslim (2849) narrated that Abu Sa‘eed al-Khudri (may Allah be
pleased with him) said: The Messenger of Allah (blessings and peace of Allah
be upon him) said: “Death will be brought in the form of a black and white
ram, then a caller will call out: O people of Paradise! And they will crane
their necks and look. He will say: Do you recognise this? They will say:
Yes; this is death – and all of them will have seen it. Then he will call
out: O people of Hell! And they will crane their necks and look. He will
say: Do you recognise this? They will say: Yes; this is death – and all of
them will have seen it. Then it will be slaughtered, then he will say: O
people of Paradise, it is eternal and there will be no death. O people of
Hell, it is eternal and there will be no death.”

Sixthly:

We advise the
questioner not to occupy himself with such questions that may lead to
confusion and frustration, and in which there is no great benefit. He should
focus on that which is more useful and more beneficial, such as asking about
Islamic rulings that he needs to know, and issues having to do with sound
belief that he is enjoined to believe in, and virtuous deeds that will bring
him closer to his Lord, and so on.

And Allah knows
best.
