It could be possible that jinns are responsible for alien/paranormal activity. There has been some research done by Ellen Rosemary on this subject -
This is what the Quran says about the jinns:
1. What are the jinns?
The jinn are among the creatures that Allah (swt) created. The jinn race was created from fire.
"And the Jinn race, We had created before, from the fire of a scorching wind." (Quran 15:27)
They have intellect, freedom and power to choose between right and wrong. These characteristics suit the need for them to worship God.
"I have only created Jinns and men, that they may serve Me." (Quran 51:56)
They are being hold responsible for all their actions like humans do in the Judgement Day.
"On that Day no question will be asked of man or Jinn as to his sin." (Quran 55:39)
The jinn with sins are going to be placed in Hell.
He will say: "Enter ye in the company of the peoples who passed away before you - men and jinns, - into the Fire." (Quran 7:38)
Satan on the other hand is the enemy to mankind.
"Said (the father): "My (dear) little son! relate not thy vision to thy brothers, lest they concoct a plot against thee: for Satan is to man an
avowed enemy!" (Quran 12:5)
Satan are consisted of both men and jinns.
"Likewise did We make for every Messenger an enemy,- evil ones among men and jinns, inspiring each other with flowery discourses by way of deception.
If thy Lord had so planned, they would not have done it: so leave them and their inventions alone." (Quran 6:112)
2. Can they bother us or invade our bodies or hurt us?
Yes, Jinn and Satan (Jinn) can posses people according to this verse:
"Those who devour usury will not stand except as stand one whom the Evil one by his touch Hath driven to madness..."
Prophet Ayyub a.s. was afflicted with distress and suffering by the Satan (Jinn). It was recorded in the Quran in this verse:
Commemorate Our Servant Job. Behold he cried to his Lord: "The Evil One has afflicted me with distress and suffering!"
3. What is their purpose other than to worship Allah(swt)?
No other purpose than to worship Allah since Allah Himself has said this:
"I have ONLY created Jinns and men, that they may serve Me." (Quran 51:56)
4. Can we see them?
Naturally we can't according to this verse:
O ye Children of Adam! Let not Satan seduce you, in the same manner as He got your parents out of the Garden, stripping them of their raiment, to
expose their shame: for he and his tribe watch you from a position where ye cannot see them: We made the evil ones friends (only) to those without
But still there is an exception cases when they change their natural forms and appear in front of humans so that they can be seen. In the light of
Hadith, Jinn have been given power to change their form and appear in front of human beings in various forms; such as an animal, a reptile, or even a
Satan, who is also from the family of Jinn, came in the form of an old man on the day of Badr (the famous battle in the year 2 A.H.). He tried to
uplift the morals of the kafir fighters but when he saw the army of the angels descending to aid the Muslims, he could not bear the sight of them and
Mujahid, a student of Ibn Abbas says:-
“After Ibn Abbas’s death a satan would constantly appear before me in the form of Ibn Abbas whenever I started prayer. This got so worse that at
times I was forced to break my prayer. So I decided to confront him next time he appeared and so I hid a dagger in my pocket and started prayer. When
he came in front of me, I took out the dagger and jumped on him. He disappeared instantly and therafter he never came back.”
