JIN is one kind of creature of Allah Subhanahu wa Taala who has certain physical properties, different from the type of man or angel. The genie is created from the substance of fire, as Allah Almighty says, "He created man from dry land like pottery, And He created the jinn from the flame of fire." (Surat ar-Rahman: 14 15)
The genie has something in common with humans in two ways:
a. The genie has reason and lust, as humans also have reason and lust.
b. Jin gets the burden of the command and the prohibition of shari'a, as the mausia also gets the burden of the command and the prohibition of shari'a. Therefore, there are jinn who are muslim and there are jinn who disbelieve. There is a good djinni and there is a evil djinni. There are jinn who are clever religious matters and there are dumb jinn. There are even jinn of Ahlussunnah and there are jin followers of heretical groups, and so on.
Whereas the difference of genie with the most basic human is from the origin of creation and the ability can be seen and not. This creature is called jinn, because it has the nature of ijtinan, which means hidden and invisible. Man can not see jinn and jinn can see man. Allah says,
"Surely he (the devil) and his followers see you in a state that you can not see them." (Surah Al-Araf: 27)
