Is epilepsy caused by the jinn?

Question :
Since epilepsy is caused by jinn, how do we explain the black woman who came to the Prophet (saaws) asking for him to invoke Allah for her cure of her illness of epilepsy and coming uncovered, but there was no mention of jinn possession? Or is there a mistake in translation and it wasn't really epilepsy?

Answer :
Praise be to Allaah.
Epilepsy in most cases is caused by the jinn, and in some cases by some defect in the body, brain or nerves, or mood swings, or some weakness in the physical structure. All of these may cause loss of consciousness or unbalanced behaviour. The black woman’s epilepsy may have been caused by the jinn, but there was no need to mention the cause, which is why the narrators only mentioned what needs to be done when epilepsy occurs, for whatever reason, of making du’aa’ and performing ruqyah, or bearing it with patience and seeking the reward from Allaah. more...
