Can jinn truly enter a human body and control its actions, and do they have their own world, dwellings, and restaurants?

The possession of a human by jinn is a real and known matter, supported by evidence from the Qur’an and Sunnah, such as the Almighty’s saying: "Those who consume interest will not stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity," and the hadith of the black woman. It is not known how jinn enter the human body, and they do not have control over a person’s actions. However, Allah may give them power over some of His creation.
