Surah 55. Ar-Rahman, Ayah 15

Cf. 15:27 - "the fire of scorching winds (nar as-samum)" - thus stressing their non-corporeal origin and composition. The significance of the term jinn ("invisible beings") has been touched upon briefly in note [86] on 6:100 and note [67] on 37:158 ; for a more detailed explanation, see Appendix III.

For the meaning of Jinn, see n. 929 to vi. 100. They are spirits, and therefore subtle like a flame of fire. Their being free from smoke implies that they are free from grossness, for smoke is the grosser accompaniment of fire.
