Why does Islam teach its followers to abstain from pleasure and amusement, and keep them always in a state of misery?

Your idea of asking an Islamic website is good and indicates your desire for knowledge. We assure you that you did not ask for amusement, but to increase your knowledge.

1. "Custom," "taste," and "law" impose restrictions on human freedom. If that is the case, then why the surprise that Allah Almighty and religion have authority over people? The Muslim student's actions of not going to the nightclub and not drinking intoxicants were done because Allah Almighty forbade him from doing so. 2. We ask you: Is there a limit to pleasure? Would you be content for your girlfriend or wife to be shared by others? Islam has forbidden sexual relations outside the framework of marriage to protect societies and shield them from diseases. 3. The world is the prison of the believer and the paradise of the disbeliever. The true pleasure for the believer is in the hereafter, while the pleasure of the disbeliever is only in this world. 4. Islam does not forbid pleasure; rather, it permits and defines it in a way that preserves a person's dignity, health, and soul. True pleasure lies in permissible things, and disobedience is followed by regret.
