Super efficiency

An-namal
[قَالَ يأَيُّهَا الْمَلأ أَيُّكُمْ يَأْتِينِى بِعَرْشِهَا قَبْلَ أَن يَأْتُونِى مُسْلِمِينَ - قَالَ عِفْرِيتٌ مِّن الْجِنِّ أَنَاْ ءَاتِيكَ بِهِ قَبْلَ أَن تَقُومَ مِن مَّقَامِكَ وَإِنِّى عَلَيْهِ لَقَوِىٌّ أَمِينٌ - قَالَ الَّذِى عِندَهُ عِلْمٌ مِّنَ الْكِتَـبِ أَنَاْ ءَاتِيكَ بِهِ قَبْلَ أَن يَرْتَدَّ إِلَيْكَ طَرْفُكَ فَلَمَّا رَءَاهُ مُسْتَقِرّاً عِندَهُ قَالَ هَـذَا مِن فَضْلِ رَبِّى لِيَبْلُوَنِى أَءَشْكُرُ أَمْ أَكْفُرُ وَمَن شَكَرَ فَإِنَّمَا يَشْكُرُ لِنَفْسِهِ وَمَن كَفَرَ فَإِنَّ رَبِّى غَنِىٌّ كَرِيمٌ ]
38. He said: "O chiefs! Which of you can bring me her throne before they come to me surrendering themselves in obedience (as Muslims)'') (39. An `Ifrit from the Jinn said: "I will bring it to you before you rise from your place. And verily, I am indeed strong and trustworthy for such work.'') (40. One with whom was knowledge of the Scripture, said: "I will bring it to you within the twinkling of an eye!'' Then when he saw it placed before him, he said: "This is by the grace of my Lord -- to test me whether I am grateful or ungrateful! And whoever is grateful, truly, his gratitude is for himself; and whoever is ungrateful, certainly my Lord is Rich, Bountiful.''

My note:
1. One way to look at these verses was from an efficiency analysis. Sulayman had great resources.
2. And see how he chose the most efficient way to accomplish the task.
