Is there really something called "Qareen magic," and is it the most potent type of magic, difficult to cure with Quranic verses?

We have not come across anything called "Qareen magic," and the Quran is a healing from all magic. It is not permissible to seek help from jinn (the Qareen) or to ask them about illness, because that is shirk (polytheism), and one must repent from that and restrict oneself to legal Ruqyah. The Qareen is a devil appointed over a person, commanding him to commit indecency, and it leaves him upon his death.
