The Purpose of Creation

Allah (creator) - teacher
Human and all living things (creation) - student

Analogy :

A teacher
2 Students : namely A and B

During a test, the teacher expected that 
student A will pass the test while student B will fail the test.
And so, after the test finished and marks have been given,
It showed that student A passed the test and student B failed the test.
The teacher knows that B always skip classes, didn't do his homework , etc
While A always striving hard in study and totally prepared for the test.
So, who are we going to blame?
The teacher or the student?

*with the nature of God whom omniscient, He knew every single thing 
that we do or going to do. it's just we, as His servant, 
didn't have any idea with the things that have been noted in Luh Mahfuz. 
So it's our role to struggle/make an effort in order to have His pleased upon us. 

"Verily, Allah will not change the fate of a people 
unless they change anything from themselves." 
Q.S Ar-Ra'd (Quran 13:11)
