We have not created the heavens and the earth and all that lies between them, all for nothing. Only those who deny imagine so. So for the unbelievers there is woe from the fire. 27 Shall We treat those who believe and work deeds of righteousness, the same as those who do mischief on earth? Shall We treat those who guard against evil, the same as those who turn aside from the right? 28 This is the Blessed Book that We have revealed to you, (O Muhammad), that people with understanding may reflect over its verses and those with understanding derive a lesson. 29 And We vouchsafed unto Da'ud Sulaiman. How excellent a bondman! verily he was oft-returning. 30 Recall what time there were presented unto him, at eventide, coursers swift-footed. 31 He said: "The love of horses is worthy of desire to me for the remembrance of my Lord;" and when they were out of sight, (he said): 32 He said, "Bring them back to me." Then he started to rub their legs and necks. 33 And certainly We tried Sulaiman, and We put on his throne a (mere) body, so he turned (to Allah). 34 he prayed: "O my Sustainer! Forgive me my sins, and bestow upon me the gift of a kingdom which may not suit anyone after me: verily, Thou alone art a giver of gifts!" 35 Then We subjected the wind to his power, so that it blew gently, at his behest, wherever he willed, 36 And the devils -- the builders and divers of all kinds, 37 and others also, coupled in fetters: 38 This is Our gift, so bestow thou or withhold, without rendering an account. 39 And verily for him is an approach with Us, and a happy end. 40
