۞ And indeed We gave Dawud the utmost excellence from Us; “O the hills and birds, repent towards Allah along with him”; and We made iron soft 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 And unto Solomon (We gave) the wind, whereof the morning course was a month's journey and the evening course a month's journey, and We caused the fount of copper to gush forth for him, and (We gave him) certain of the jinn who worked before him by permission of his Lord. And such of them as deviated from Our command, them We caused to taste the punishment of flaming Fire. 12 fashioning for him whatsoever he would -- places of worship, statues, porringers like water-troughs, and anchored cooking-pots. 'Labour, O House of David, in thankfulness; for few indeed are those that are thankful among My servants.' 13 But when We decreed death for him, naught showed them his death but a creature of the earth that ate away his staff; and when it fell down, the jinn came to know plainly that if they had known the unseen, they would not have tarried in abasing torment. 14 There was for [the tribe of] Saba' in their dwelling place a sign: two [fields of] gardens on the right and on the left. [They were told], "Eat from the provisions of your Lord and be grateful to Him. A good land [have you], and a forgiving Lord." 15 But they turned away and so We let loose upon them a devastating flood that swept away the dams and replaced their gardens by two others bearing bitter fruits, tamarisks, and a few lote trees. 16 This We requited them with because they disbelieved; and We do not punish any but the ungrateful. 17 Now [before their downfall,] We had placed between them and the cities which We had blessed [many] towns within sight of one another; and thus We had made traveling easy [for them, as if to say]: "Travel safely in this [land,] by night or by day!" 18 But they said: "Our Lord! Make the stages between our journey longer," and they wronged themselves, so We made them as tales (in the land), and We dispersed them all, totally. Verily, in this are indeed signs for every steadfast grateful (person). 19 And assuredly Iblis found his conjecture true concerning them; and they followed him all save a party of the believers. 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
