The Holy Book states that God bestowed upon the House of Abraham the Scripture and Wisdom and He bestowed on them a mighty kingdom (4:54). The mighty kingdom bestowed upon the House of Abraham manifested itself most brilliantly through the Prophets David and Solomon. The Prophet Solomon ruled not only over a part of mankind but also over jinn devils birds and winds:

"God subdued unto him devils some of whom dived for pearls and did other work (21:82)."

He had armies of jinn and birds and he employed jinn in many jobs:

"They made for him what he willed: synagogues fortresses and basins like wells and boilers built into the ground (34:13).

"Wind was also subdued to him; its morning course was a month's journey and the evening course also a month's journey (34:12)."

As was pointed out earlier the throne of the Queen of Sheba was carried from the Yemen to Jerusalem in the twinkling of an eye (27:40).

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. It is quite probable that they will also be employed in security affairs; mining and metal work and even in space studies and historical researches. Since Jinn can live about one thousand years they may be useful in establishing historical facts.
