There are two aspects to fear caused by the jinn, one which is correct and one which is incorrect. The correct aspect is to note that there are some jinn who can overpower humans and make them hear voices and see things, and feel that someone is following them and make them scared inside their own homes.
The way to deal with this is to recite the Qur'an, regularly recite the Adhkaar for morning and evening, and follow a special program for the sick person. The incorrect aspect is the great fear of the jinn that is deeply-rooted in many people. There is nothing to justify such fear from an Islamic point of view. Hence we will outline the reasons why people have developed such fear at the very mention of the jinn, and then we will be able to put our finger on the problem and find the remedy.
It should be noted that the jinn are not all ugly and dark as they appear in the stories of possession and causing fear and harm. There are some jinn who are more righteous than humans, and some jinn have a glowing record of faith, piety and calling others to Allah (SWT), as is mentioned at the beginning of Surah Al- Jinn which speaks of a group of jinn who listened to the Qur'an being recited on the lips of the Messenger and they went back and warned their people.
