۞ We granted David a favor by commanding the mountains and birds to sing Our praise along with him and softened iron for him 10 [and inspired him thus:] "Do good deeds lavishly, without stint, and give deep thought to their steady flow." And [thus should you all, O believers,] do righteous deeds: for, verily, I see all that you do! 11 To Solomon the morning course of the wind was a month's journey, and its evening course was also a month's journey. We caused copper to be (as a) molten spring for him. And the jinn, some served him by the permission of his Lord. But as for those amongst them that swerved away from Our Command, We shall let them taste the punishment of the Blaze (the Fire). 12 they made for him whatever he wished of sanctuaries, and statues, and basins as [large as] great watering - troughs, and cauldrons firmly anchored. [And We said:] "Labour, O David's people, in gratitude [towards Me] and [remember that] few are the truly grateful [even] among My servants!" 13 Yet [even Solomon had to die; but] when We decreed that he should die, nothing showed them that he was dead except an earthworm that gnawed away his staff. And when he fell to the ground, those invisible beings [subservient to him] saw clearly that, had they but understood the reality which was beyond the reach of their perception, they would not have continued [to toil] in the shameful suffering [of servitude] 14 Indeed for (the tribe of) Saba was a sign in their dwelling-place – two gardens on the right and the left; “Eat the sustenance provided by your Lord and be grateful to Him”; a pure land and an Oft Forgiving Lord! 15 In response they turned away – We therefore sent upon them a tremendous flood, and in exchange of their two gardens gave them two gardens bearing bitter fruit, and tamarisk, and some berries. 16 Thus did We retribute them for their ingratitude. And none do We retribute in this manner except the utterly ungrateful. 17 We placed other prominent towns between them, the towns that We had blessed and had set well-measured stages between them. Move back and forth between them, night and day, in perfect security. 18 But they said: 'Lord, make the stages between our journeys longer' so they wronged themselves; so We made them news and We tore them utterly into pieces. Surely, there are signs in this for every one who is patient, thankful. 19 And Satan indeed found his calculation true concerning them, for they follow him, all save a group of true believers. 20 But he had no authority over them,- except that We might test the man who believes in the Hereafter from him who is in doubt concerning it: and thy Lord doth watch over all things. 21
