The Djinn are said to be creatures with free will, made from ‘smokeless fire’ by Allah in the same way humans were made of earth. According to the Qur’an, Djinn have free will, and Iblees used this freedom in front of Allah by refusing to bow to Adam when Allah told Iblees to do so. By refusing to obey Allah order he was thrown out of the Paradise and called “Shaitan”. Djinn are frequently mentioned in the Qur’an, Sura 72 of the Qur’an (named Al-Jinn) is entirely about them. Another Sura (Al-Naas) mentions the Djinn in the last verse. It is also mentioned in the Qur’an that Muhammad was sent as a prophet to both “humanity and the Djinn”.
In the world there are three main creations, Angels, Humans and Jinns (other than various animals):
Angels: Angels are made from light (Noor). In Islam they are slaves of God who have no free will. They do not commit any sin nor disobey God and they always worship him.
Humans: Humans are created from earth and are given free will to do good or bad in their lives. Because of their free will, they will be held accountable for their choices in this life on the Day of Judgement. Those who follow and obey God (Allah), will be rewarded with paradise/heaven.
Jinns: Similar to humanity, jinns have free will allowing them to follow any religion they choose to, such as Islam, Christianity, Judaism, Hinduism, etc. The only difference is that they are made of smokeless fire and therefore are not visible to humans. There are more jinns than humans, in terms of population. Jinns have the power to fly and fit in to any space so they live in remote areas, mountains, seas, trees, and in the air, in their own communities. Similar to the humans, Jinns will also be judged on The Day of Judgement and will be sent to Jannat (heaven) or Nar (hell) according to the life they lead.
