No one knows the unseen in the absolute sense except Allaah

I want to know that Quran says that only Allah knows the Unseen. But i
found out in a hadith that Prophet PBUH told us that Jinn the
fortuneteller a part of truth and then fortune teller mix it witha
hundred lies and tells to us , In another hadithsProphet PBUH tells us
that Astrology is only based on lies " Sun and Moon are only Signs of
Allah"
So How does Jinn tells the fortune while only Allah knows the Fortune?.
Praise be to Allaah.
Knowledge of the unseen is something that Allaah has kept for Himself,
as is indicated by the texts of the Qur'aan and Sunnah. Allaah says
(interpretation of the meaning):
"Say: "None in the heavens and the earth knows the Ghaib (Unseen)
except Allaah, nor can they perceive when they shall be resurrected"
[al-Naml 27:65]
"And with Him are the keys of the Ghayb (all that is hidden), none
knows them but He. And He knows whatever there is in the land and in
the sea; not a leaf falls, but He knows it. There is not a grain in
the darkness of the earth nor anything freshor dry, but is written in
aClear Record"
[al-An'aam 6:59]
The Prophet (peace and blessings of Allaah be upon him) explained
these keys as referring to five things which are mentioned in Soorat
Luqmaan, where Allaah says (interpretation of the meaning):
"Verily, Allaah, with Him (Alone) is the knowledgeof the Hour, He
sends down the rain, and knows that which is in the wombs. No person
knows what he will earntomorrow, and no person knows in what land he
will die. Verily, Allaah is All-Knower, All-Aware (of things)"
[Luqmaan 31:34].
Al-Bukhaari narrated in his Saheeh (hadeeth no. 4477) that 'Aa'ishah
(may Allaah be pleased with her) said: "Whoevertells you that he knows
what will happen tomorrow is lying." Thenshe recited, "No person knows
what he will earntomorrow."
But with regard to this matter it is important to know what is the
unseen the knowledge of which Allaah has kept to Himself, because
al-ghayb (the unseen) means that which is not seen, and that which is
not seen may be either that which is not seen byall of creation - both
those who are in the heavens and those who are on earth - this kind of
unseen is known to no one but Allaah, and this is that which is called
al-ghayb al-mutlaq (the unseen in the absolute sense); or this unseen
matter may be unseen for some people, and known to some others. This
is called unseen for the one who is ignorant of it, but it is not
unseen or unknown to all people, and knowledge of it is not unique to
Allaah. Shaykh Ibn 'Uthaymeen (may Allaah have mercy on him) said in
Sharh al-'Aqeedah al-Waasitiyyah (p. 158): What is meant by the unseen
is that which is not seen. The unseen is something relative. But that
which is unseen in the absolute sense (al-ghyab al-mutlaq) is known
only to Allaah. End quote.
What fortune-tellers say of things that will happen in the future
hasnothing to do with the unseen or with knowledge of the unseen, and
it is not knowledge of what will happen in the future. Rather they are
liars who make false claims. But the Prophet (peace and blessings of
Allaah be upon him) has told usthat they steal knowledge of that which
Allaah has revealed to His angels. It was narrated that 'Aa'ishah (may
Allaah be pleased with her) said: Some people asked the Prophet (peace
and blessings of Allaah be upon him) about fortune-tellers, and he
said: "They are nothing."They said: O Messenger of Allaah, they say
something and it comes true. The Prophet (peaceand blessings of Allaah
be upon him) said: "Thatis a word of truth which the jinni snatches
and cackles into the ear of his familiar like the cackling of a hen,
and they mix more than one hundred lies with it." Narrated by
al-Bukhaari (7561).
The Prophet (peace and blessings of Allaah be upon him) explained how
the jinn steal this word. He said: "...when our Lord, may His name be
blessed and exalted, decrees some matter, the bearers of the Throne
glorify Him, then the people of heaven who are closest to them glorify
Him, until the tasbeeh reaches the people of the lowest heaven. Then
those who are nearest to the bearers of the Throne say: What did your
Lord say? And they tell them what He said. And the people of heaven
ask one another for the news, until the news reaches the lowest
heaven. Then the eavesdropping jinn snatch what they can and convey it
to their familiars. What they narrated as they heard itis true, but
they add lies to it." Narrated by Muslim (2229).
From this it is clear that the jinn do not have knowledge of the
unseen, rather they stealwords that they hear from the angels, but the
angels themselves do not have any knowledgeof that unless Allaah tells
them of it. After they are told of it, it is no longer regarded as
unseen in the absolute sense, but before that they are like anyone
else in creation and do not know anything of the unseen. This depends
on Allaah's telling them of it. Allaah says (interpretation of the
meaning):
""(He Alone is) the All-Knower of the Ghayb (Unseen), and He reveals
to none His Ghayb (Unseen)"
[al-Jinn 72:26].
Shaykh Ibn 'Uthaymeen (may Allaah have mercy on him) said: The
noblestof the angelic Messengers, Jibreel, asked the noblest of the
human Messengers, Muhammad (peace and blessings of Allaah be upon
him), "Tell me about the Hour." He said:"The one who is asked about it
is does not know any more about it than the one who is asking"
meaning, just as you have no knowledge of it, I have no knowledge of
it either. End quote.
