Dought & clear, - Is man’s fate pre-destined or does he have freedom of will?.

Is our fate completely pre-destined? Some say we have a choice of
which path to choose but what you will find at the end of the path has
been chosen for you by Allah. I have also read that qadar was perhaps
created by Jahm b. Safwan, not Allah.
Where can I find the information in the Quran and if there is a set
destiny how much of it is chosen by God? Is there really a set day on
which I will have birth and another for earthly death, for whom I will
marry?
What if I did meet the man I am supposed to marry but I somehow choose
the wrong path (so I may believe) only to realize I did wrong. Will he
come in my path again or have I altered my destiny so that my
punishment may be that I can not have this person in my life?.
Praise be to Allaah.
Belief in al-qadar (the divine will and decree) is one of the pillars
of faith, because the Prophet(peace and blessings of Allaah be upon
him) said, when he answered Jibreel's question about faith: "(It
means) believing in Allaah, His angels, His Books, His Messengers and
the Last Day, and to believe in al-qadar (the divine decree) both good
and bad."
What is meant by al-qadar is that Allaah has decreed all things from
eternity and knows that they will happen at times that are known to
Him, and in specific ways, and that He has written that and willed it,
and they happen according to what He has decreed. [al-Qada'
wa'l-Qadarby Dr 'Abd al-Rahmaan al-Mahmoud, p. 39].
Belief in al-qadar is based on four things:
1 - Knowledge, i.e., that Allaah knows what His creation will do, by
virtue of His eternal knowledge.
2 - Writing, i.e., that Allaah has written the destiny of all
creatures in al-Lawh al-Mahfooz.
3 - Will, i.e., that what Allaah wills happens and what He does not
will does not happen. There is no movement in the heavens or on earth
but it happens by His will.
4 - Creation and formation, i.e., that Allaah is the Creator of all
things, including the actions of His slaves. They do their actions in
a real sense, and He is the Creator of them and of their actions.
Whoever believes in these four believes in al-qadar.
The Qur'aan affirms these things in numerous verses, such as the
verses in which He says (interpretation of the meaning):
"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 fresh or dry, but is written in
a Clear Record"
[al-An'aam 6:59]
"No calamity befalls on the earth or in yourselves but it is inscribed
in the Book of Decrees (Al-Lawh Al-Mahfooz) before We bring it into
existence. Verily, that is easy for Allaah"
[al-Hadeed 57:22]
"And you cannot will unless (it be) that Allaah willsthe Lord of the
'Aalameen (mankind, jinn and all that exists)"
[al-Takweer 81:29]
"Verily, We have created all things with Qadar (Divine Preordainments
of all things before their creation as written in the Book of
DecreesAl-Lawh Al-Mahfooz)"
[al-Qamar 54:49]
Muslim (2653) narrated that 'Abd-Allaah ibn 'Amr ibn al-'Aas said: I
heard the Messenger of Allaah(peace and blessings of Allaah be upon
him) say: "Allaah wrote down the decrees of creation fifty thousand
years before He created the heavens and the earth." He said: "And His
Throne was upon the water."
Hence it should be clear to you that the view that al-qadar was
invented by al-Jahm ibn Safwaan is a view that has no sound basis.
Al-qadar was not created, rather creation comes under the heading of
belief in al-qadar. Al-Jahm went to extremes in affirming the divine
will and decree, and claimed that people are compelled to do what they
do and have no choice. This is a false view.
The belief of Ahl al-Sunnah wa'l-Jamaa'ah is that a person has freedom
of will, and hence he will be rewarded or punished. But his will is
subject to the will of Allaah, and nothing can take place in the
universe that is not willed by Allaah.
What some people say, that we have the choice to follow whatever path
we want but at the end of this path you will find what Allaah has
decreed for you, is a correct view. Allaah says (interpretation of the
meaning):
"Verily, We showed him the way, whether he be grateful or ungrateful"
[al-Insaan 76:3]
"And shown him the two ways (good and evil)?"
[al-Balad 90:10]
"And say: "The truth is from your Lord." Then whosoever wills, let him
believe; and whosoever wills, let him disbelieve"
[al-Kahf 18:29]
Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said,
explaining the view of Ahl al-Sunnah with regard to man's deeds:
People act in a real sense, and Allaah is the Creator of their
actions. A person may be a believer or a kaafir, righteous or immoral,
he may pray and fast. People have control over their actions, and they
have their own will, and Allaah is the Creator of their control and
will, as Allaah says (interpretation of the meaning):
"To whomsoever among you who wills to walk straight.
And you cannot will unless (it be) that Allaah willsthe Lord of the
'Aalameen (mankind, jinn and all that exists)"
[al-Takweer 81:28-29]
al-Waasitiyyah ma'a Sharh Harraas, p. 65.
Marriage is one of the things that Allaah has decreed. The person whom
you will marry is known to Allaah: He knows who he is, when he was
born, where and when he will die, how he will be towards you, and
other details. All of that is known to Allaah and He has written it in
al-Lawh al-Mahfooz (the Book of Decrees), and it will inevitably come
to pass as Allaah has decreed.
If Allaah has decreed that you will marry one person, but you choose
someone else, then no matter how long it takes, you will marry that
person. But your marriage to someone else is also decreed, because
there is nothing that is not decreed by Allaah. It may be decreed for
a woman to marry So and so the son of So and so, and he comes to
propose marriage but she refuses him, and marries someone else, then
he (the second man) dies or divorces her, then she accepts the first
one. All of that is decreed, and it is decreed for her to marry So and
so the son of So and so after initially refusing him and after some
experience or trials etc.
It may be decreed for a woman that a righteous man will propose
marriage to her, but she will refuse him and he will never come back
to her, and she will marry and live with someone else who is more or
less righteous, according what Allaah has decreed.
Because man does not know what is decreed for him, what he must do is
to adhere to sharee'ah and abide by its commands and prohibitions, and
to seek the help of Allaah and pray to Him for guidance (istikhaarah)
concerning all his affairs, whilst implementing the means, one of the
most important of which is consulting sincere people who have relevant
experience.
If a righteous man proposes marriage to a woman, she should pray to
Allaah for guidance (istikhaarah) and agree to marry him. If things
then go smoothly, this is an indication that what is good for her is
to marry him.
In conclusion, man should study the sharee'ah of Allaah and follow the
commands of Allaah even if he feels reluctant, and avoid what Allaah
has forbidden even if he is attached to it. All goodness is to be
found in obeying sharee'ah. Allaah says (interpretation of the
meaning):
"Jihaad(holy fighting in Allaah's Cause) is ordained for you (Muslims)
though you dislike it, and it may be that you dislike a thing which is
good for you and that you like a thing which is bad for you. Allaah
knows but you do not know"
[al-Baqarah 2:216]
He should not look at al-qadar as an excuse to ignore commands and do
forbidden things, rather he should look at it in a way that will make
him content with whatever painful experiences happen to him.
And Allaah knows best.
