The Qur'aan and Sunnah indicate that the jinn exist, and that there is a purpose for their existence in this life, which is to worship Allaah Alone, with no partner or associate. Allaah says (interpretation of the meanings):
"And I (Allaah) created not the jinns and humans, except they should worship Me (Alone)." [al-Dhaariyaat 51:56].
"O assembly of jinns and mankind! Did there not come to you Messengers from amongst you, reciting unto you My Verses...?" [al-An'aam 6:130]
The world of the jinn is an independent and separate world, with its own distinct nature and features that are hidden from the world of humans. Jinns and humans have some things in common, such as the possession of understanding and the choice between the way of good and the way of evil. The word jinn comes from an Arabic root meaning "hidden from sight". Allaah says (interpretation of the meaning):
"...Verily he [Shaytaan] and his qabeeluhu [his soldiers from the jinn or his tribe] see you from where you cannot see them..." [al-A'raaf 7:27]
Allaah has told us in His Book the essence from which the jinn were created. He says (interpretation of the meaning):
"And the jinn, We created aforetime from the smokeless flame o fire." [al-Hijr 15:27]
"And the jinns did He create from a smokeless flame of fire." [al-Rahmaan 55:15].
According to a hadeeth narrated by 'Aa'ishah, the Prophet (peace and blessings of Allaah be upon him) said: "The angels were created from light, the jinn were created from fire, and Aadam was created from that which has been described to you." (Reported by Muslim, 5314).
