Why does Allah punish people in the hereafter? Would it not be more reasonable to punish in the world?

A judge must punish a person who has committed a crime. If that person is not punished, that criminal will not come to his senses and commit that crime again, but the situation is different on the Day of Judgment. When the veil of testing is removed for the person who commits a crime, he will not commit that crime again. Is punishment not imposed to people in order to get them to come to their senses and to realize justice?  One way or another, people will come to their senses on the Day of Judgment. Then, why does Allah punish people on the Day of Judgment rather than on earth? What is the point of punishing on the Day of Judgment? Will it be not justice only? If He had punished them in the world, not on the Day of Judgment, it would have been both fair and the punished person would have been wiser (he would not have done it again and the world would have been a better place).
Would it not have been more reasonable (God forbid) for Allah to punish that criminal while he was still in this world?

Dear Brother / Sister,

Why does Allah punish people in the hereafter, Would it not be more reasonable to punish in the world?

A judge must punish a person who commits a crime. If a person is not punished, the criminal will not come to his senses and repeats the crime, but on the Day of Judgment, the situation is different. When the veil of testing is removed for the person who commits a crime, he will not commit that crime again. Is punishment not imposed to people in order to get them to come to their senses and to realize justice?  One way or another, people will come to their senses on the Day of Judgment.

Then:

What is the point of punishing on the Day of Judgment? Will it be not justice only? If He had punished them in the world, not on the Day of Judgment, it would have been both fair and the punished person would have been wiser (he would not have done it again and the world would have been a better place).

Would it not have been more reasonable (God forbid) for Allah to punish that criminal while he was still in this world?

This world is a place of testing, and the reward for the deeds will be given in the Hereafter, and people will live an eternal life in Paradise or Hell.

The fact that Allah does not directly prevent evil in this world is because we are in the world of testing. This world is a test hall; both those who do wrong and those who do right are allowed. If there was an intervention for those who do wrong, the test room would have no meaning. If roses were thrown on the heads of those who did good deeds and thorns were thrown on the heads of those who sinned, this world would no longer be a test hall; everyone would have to pray and to cover themselves, whether they wanted to or not.

That is to say, it is a necessity of wisdom that there should be no punishment in the testing room that would force people to believe, worship and avoid sins by removing their will.

However, from time to time, the rewards or penalties of deeds are also given in this world.

For example, many tribes were destroyed and punished in this world for denying their prophets.

Almighty Allah tells us about the stories of the Prophets with their nations so that we can learn lessons.

Likewise, people who murder, steal, rob and commit adultery are punished in this world. Again, it is stated in hadiths that those who disobey parents and those who commit such acts will be punished while they are in the world.

The fact that sins cause remorse and uneasiness can also be described as advance punishments.

On the other hand, unbelief and shirk (worshipping any being other than Allah) are such great sins that their punishment does not fit into this mortal worldly life. So is the reward of faith.

In summary, it is both more logical and wiser not to impose a punishment that removes the will of man in this worldly life, which is a test hall, and to postpone the punishment to the Hereafter.
