Why did Allah created this world ? why is he testing humans ?

Q,''Almighty Allah knows everything the past the present the future why Allah created the world ??  

Why does he put us to jannt or  jhnnm directly ???

Answer;
Allah knows everything who are jhnnmi and who are  jnnati  if Allah will tell someone  u r born u go to hell he will  object ...

Bt Allah knows at the end of  time u will go to hell 

 Will he go ??

Fr example  ;; in class  room a teacher  is teaching a clsroom fr a year  teacher knows who is going to pass who is going ta fail 

Now if teacher tell ... no exam ... u r  failed.  Nd u r failed ..

Will  u agree  it  or object 

Even u know u r going to fail??

Allah knows in advance but if Allah says  u go to hell 

U will object nd say why should i go to hell that's why u make choice nt Allah 

Now question comes abt destiny 

Tht everything is written in destiny whether I am going to jannati or jahnnmi

If everything is written in destiny  then If my destiny is written tht im jhnnmi then who is going to blame??

Allah is going to blame???

Or who??

For example;;

If teacher predicts that the students will fail

Nd u will fail  who is to blame?

Teacher or student??

Of course student!!

Because teacher knows tht the  students used to bunk cls he used play hockey!! 

Now here Allah gives u choice  tht this the way if u follow u wiil go to jannt if u nt flow u will go to jhnnm bt u r the person who is  going to choose?? Nt Allah  

Here if Allah puts the moment u born in hell u will object why u r putting me in hell 

"""In quran Allah says" on the day of judgment no unbelievers would ever question to the justices of Allah they will only say plz give us one more chance nd Allah will say it's over """

So this life is test fr here after the choices urs allah has given u the guidance  in the quran ""
