[Pooya/Ali Commentary 72:6] The inability of the human beings, particularly in the earlier ages of ignorance, to understand the nature of created beings other than themselves, led them to believe in false notions about the jinn. They thought that the jinn had mysterious powers and could harm them in supernatural ways, so they began to give undue importance to the jinn, and many people used to invoke them for protection and safety. This attitude of man made the jinn proud and they foolishly and falsely assumed the responsibility of guarding and protecting mankind. Like the disbelievers some among the jinn also thought that there is no resurrection and judgement, so they became daring and tried to pry higher realms but their dark plots were defeated by vigilant guards described as the shafts of meteoric light in the heavens. See commentary of Hijr: 16 to 18; Saffat: 7 and Mulk: 5.
