۞ And We gave David bounty from Us: 'O you mountains, echo God's praises with him, and you birds!' And We softened for him iron: 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 AND UNTO Solomon [We made subservient] the wind: its morning course [covered the distance of] a month's journey, and its evening course, a month's journey. And We caused a fountain of molten copper to flow at his behest; and [even] among the invisible beings there were some that had [been constrained] to labour for him by his Sustainer's leave and whichever of them deviated from Our command, him would We let taste suffering through a blazing flame: 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 Then when We decreed death for him, naught discovered his death to them save a moving creature of the earth which gnawed away his staff. Then when he fell, the jinn clearly perceived that if they had known the unseen they would not have tarried in the ignominious torment. 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 But they turned away. So We sent against them the Flood (at the city) of Arim, and exchanged their gardens with two others bearing bitter fruit and Tamarisks, and here and there a few Lotus trees. 16 That is how We requited them for their ingratitude. We only punish those who are ungrateful. 17 We established between them and the town that We had blessed, other towns nearby, and thus made it easier to travel. We told them, "Travel there safely day and night". 18 They said, "Lord, make the distances of our journeys longer." They did injustice to themselves and We turned their existence into ancient tales by making them disintegrate totally. In this there is evidence (of the truth) for every forbearing and grateful person. 19 And indeed Iblis made his assumptions regarding them seem true, so they all followed him except the group of Muslims. 20 And he had over them no authority except [it was decreed] that We might make evident who believes in the Hereafter from who is thereof in doubt. And your Lord, over all things, is Guardian. 21
