The Jinns were created by Allah Almighty as people. Like people, jinns live, reproduce, marry, eat, etc. The habitat of the jinn is the human body, where they perform all their actions. The jinns feed on human blood. Therefore, people, in which the jinns have settled, often suffer from anemia, fall into depression.
The jinns can cause all sorts of diseases and problems, the cause and essence of which in most cases is not possible to determine.
Strong djinn said: "I will bring it to you before you rise from your place (council). And verily, I am indeed strong, and trustworthy for such work'.
A certain ifrit from the jinn came to bring the throne. The Arabic word ifrit means "very strong"; "diligent". Suleiman's kingdom was in Sham, and in order to transport the throne of the Sabean queen in the usual way it would take about four months: two months to get to Yemen, and two months to return from there to Sham. Despite this, the mighty genie undertook to bring him a huge and difficult throne before he left the meeting. Important meetings usually last almost all morning. They can last a third of a day or more. You can imagine what a great ruler was the prophet Suleiman, if he had such powerful and powerful subjects
Their ability to show themselves in the form of a person, animals and birds is one of the abilities that a person is forced into by a state of shock.
