The doors to the metaphysical worlds are only a little ajar yet.
Mankind are barely at the beginning of contact with jinn and devils.
However, mankind will one day feel constrained to enter the world of jinn and devils and try to solve many of their problems pertaining to the material world. The mighty kingdom bestowed upon the House of Abraham manifested itself most brilliantly through the Prophets David and Solomon, upon them be peace. As was pointed out earlier, the throne of the Queen of Saba' was carried from the Yemen to Jerusalem in the twinkling of an eye. The verses relating to Solomon's kingdom point to the final limit of the use of jinn and devils by mankind. These verses suggest that a day will come when mankind are able to use them in many jobs, especially in communication.
