Keep insulting & dodge my points
Ever heard of leibniz 'twin train theory'?
Qadar is one of the aspects of aqidah. Muslims believe that the divine destiny is when God wrote down in the Preserved Tablet (al-lawh al-mahfooz [ar]) (several other spellings are used for this in English) all that has happened and will happen, which will come to pass as written. According to this belief, a person's action is not caused by what is written in the preserved tablet, but rather the action is written in the tablet because God already knows all occurrences without the restrictions of time.On the other hand, the causal relationships are also part of Qadar, since human acts affect what is stated in the Preserved Tablet. The phrase reflects a Muslim doctrine that Allah has measured out the span of every person's life, their lot of good or ill fortune, and the fruits of their efforts. Again Allah does not need to force anyone to do good or evil by interfering with his will, and nobody will bear witness that Allah did so. When referring to the future, Muslims frequently qualify any predictions of what will come to pass with the phrase Insha'Allah, Arabic for "if God willed [it]." The phrase recognizes that human knowledge of the future is limited, and that all that may or may not come to pass is under the control and knowledge of God.
However, people are not predestined by Allah to enter Hell. Rather, people will only bear their own sins that they themselves committed with free will and no one will be responsible for another person's deeds. The Quran holds that no man will be treated unjustly and everything will be judged by Allah. The Quran says this in the following verse:
" Say: You will not be questioned as to what we are guilty of, nor shall we be questioned as to what you do. Say: Our Lord will gather us together, then will He judge between us with the truth; and He is the greatest Judge, the All-knowing."
— Quran 34:25-26
They will cry out to them: Were we not with you? They shall say: "Yes! but "you caused yourselves to fall into temptation, and you waited and doubted, and vain desires deceived you till the threatened punishment of Allah came, while the archdeceiver deceived you about Allah."
— Quran 57:14
And if Allah had known any good in them He would have made them hear, and if He makes them hear they would turn back while they withdraw.
— Quran 8:23
Nor would thy Lord be the One to destroy communities for a single wrong-doing, if its members were likely to mend. If thy Lord had so willed, He could have made mankind one people: but they will not cease to dispute. Except those on whom thy Lord hath bestowed His Mercy: and for this did He create them: and the Word of thy Lord shall be fulfilled: "I will fill Hell with jinns and men all together."
— Quran 11:119
No calamity befalls on the earth or in yourselves but is inscribed in the Book of Decrees (al-lawh al-mahfooz), before We bring it into existence. Verily, that is easy for Allah.
— Quran 57:22
A hadith reports that Muhammad said about Qadr:
Ali narrated that one day the Messenger of Allah was sitting with a wooden stick in his hand with which he was scratching the ground. He raised his head and said, “There is none of you, but has his place assigned either in the Fire or in Paradise.” They (the Companions) inquired, “O Allah’s Messenger! Why should we carry on doing good deeds, shall we depend (upon Qadar) and give up work?” Muhammad said: “No, carry on doing good deeds, for everyone will find it easy (to do) such deeds that will lead him towards that for which he has been created.” Then he recited the verse: “As for him who gives (in charity) and keeps his duty to Allah and fears Him, and believes in al-Husna, We will make smooth for him the path of Ease (goodness) (Surah al-Lail 92:5-7). Sahih Muslim
However, it is made clear that no person has the power to benefit or harm himself or others, and that guidance is only given by Allah, no one else has the power to give guidance. The Quran says:
For those who do good is good (reward) and more (than this); and blackness or ignominy shall not cover their faces; these are the dwellers of the garden; in it they shall abide.
— Quran 10:26
So the quran argues for both free will & pre-destination you focused only on 1 so the question again how can they not coexist as I explained & demonstrated ?
