Baha'i faith and the Qur'an

"Regarding your question as to the meaning of Jin or Genii referred to in the Qur'an, these are not beings or creatures that are actually living, but are symbolic references to the power of men of evil and may be likened to evil spirits. But the point to bear in mind is that these have no positive existence of any kind."

(From a letter written on behalf of the Guardian to an individual believer, June 26, 1936: Bahá'í News, No. 105, p. 1, February 1937)
