Abstract
The researcher dealt with an important topic about the content of worship, especially belief in God Almighty, and belief in the existence of jinn, which is considered one of the foundations of firm faith among believers, as well as the existence of obsessive thoughts, and denying its existence is considered a violation of what was stated in the Holy Qur’an, in which God Almighty said: Say, I seek refuge in the Lord of mankind ( 1) The King of the people (2) The God of the people (3) From the evil of the whisperer, the deceiver (4) The one who whispers in the hearts of the people (5) From Heaven and the people (6)The jinn are part of the unseen in which we must believe, and the evidence - the Qur’an, the Sunnah, and the traditions - has come together on the existence of the demons of the jinn and humans that whisper in the hearts of people. As for all of this, a person must arm himself with the weapon of faith and piety to have the ability to overcome these heart diseases. Thus, he has attained the pleasure of God Almighty and his protection from all harm.
