The article focuses on the understanding of jinn (genie) in the context of religious sources and culture. As it is known, there is a lot of verses in the Qur'an about jinn. However, the fact of jinn and its qualities are not discussed in the sources of tafsir. It is of vital importance for the believer to understanding of the Qur'an which sent by Allah. We have addressed this issue in order to contribute to the understanding of the Qur'an as authentic. To true understand a subject belonging to the Qur'an is to preserve the integrity of the subject and to observe the historical and cultural atmosphere to which the verses relate. For this reason, we have mainly used religious sources such as the Qur'an and hadiths, and secondly, the Arabic culture. The result we have reached is this: the Qur'an used the expression of jinn as adjective noun. Therefore, in the Qur'an, the expression of jinn is one of two alternatives: Physical existence with unrecognized senses and transcendent beings. However, as the jinn of Solomon the Qur'an has also used the expression of jinn in the sense of strangers and craftsmen (priests, astrologers and ingenious masters), based on Arabic cultures from time to time.
