How can the story of the dark-skinned woman who asked the Prophet for healing from epilepsy and her consequent uncovering be interpreted, and does the absence of any mention of jinn possession in the story imply an error in translation or that what afflicted her was not true epilepsy?

Epilepsy has multiple causes, most of which are due to jinn, and some are the result of physical, cerebral, nervous, or psychological disorders. The black woman mentioned in the hadith had epilepsy due to jinn, as evidenced by her saying: "I fear the evil one will strip me naked," which confirms that her epilepsy was jinn-induced.
