۞ And assuredly We vouchsafed unto Da'ud grace from us, and said: mountains! repeat Our praise with him; and also ye birds! And We softened for him the iron. 10 "Make full-length coats of mail, measuring the links well. And do righteous deeds. Surely, I see all that you do." 11 We subjected the wind to Solomon; its morning course was a month and its evening course a month; and We caused a fount of molten copper to flow for him. And of the jinn there were some who worked under him, by the command of his Lord. If any one of them turned away from Our command, We would make him taste the punishment of the burning fire. 12 They would make for him anything that he wanted like fortresses, statues, large basins like reservoirs, and huge immovable cooking pots. It was said, "Family of David, worship and act gratefully. Only few of my servants are grateful." 13 And when We decreed for Solomon death, nothing indicated to the jinn his death except a creature of the earth eating his staff. But when he fell, it became clear to the jinn that if they had known the unseen, they would not have remained in humiliating punishment. 14 For Sheba also there was a sign in their dwelling-place -- two gardens, one on the right and one on the left: 'Eat of your Lord's provision, and give thanks to Him; a good land, and a Lord All-forgiving.' 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 Like this We requited them because they were ungrateful disbelievers. And never do We requit in such a way except those who are ungrateful, (disbelievers). 17 And We placed between them and the towns which We had blessed, towns easy to be seen, and We made the stages (of journey) between them easy (saying): "Travel in them safely both by night and day." 18 but they said, "Our Lord! Make the stages of our journeys longer." Thus they wronged themselves and We made them bygone tales and scattered them throughout the land. There are certainly signs in that for everyone who is steadfast and thankful. 19 And Satan indeed found his calculation true concerning them, for they follow him, all save a group of true believers. 20 Yet he had no authority over them, but that We might know him who believed in the Hereafter from him who was in doubt thereof Thy Lord is Guardian over everything. 21
