۞ Say: 'What, do you disbelieve in Him who created the earth in two days, and do you set up compeers to Him? That is the Lord of all Being. 9 He set firm mountains on top (of the earth) and He blessed it. And in four days He ordained in it many provisions, equal to those who ask. 10 Then He turned to the heaven while it was all smoke. He said to the heaven and the earth: “Come (into being), willingly or unwillingly.” They said: “Here we come (into being) in willing obeisance.” 11 So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge. 12 But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] 'Aad and Thamud. 13 When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah" They said: "If our Lord had so willed, He would surely have sent down the angels. So indeed! We disbelieve in that with which you have been sent." 14 As for A'ad, they were arrogant in the land without right, and they said: Who is mightier than us in power? Could they not see that Allah Who created them, He was mightier than them in power? And they denied Our revelations. 15 So We let loose on them a violent wind for several days of distress to make them taste a most disgraceful punishment here in this world, and far more shameful will be the punishment in the Hereafter, and there will be no succour for them. 16 And as to Samood, We showed them the right way, but they chose error above guidance, so there overtook them the scourge of an abasing chastisement for what they earned. 17 And We delivered those who believed and had been fearing. 18
