۞ Say: 'Do you disbelieve in Him who created the earth in two days? And do you set up equals with Him? He is the Lord of the Worlds' 9 In four days He placed the mountains on it, blessed it, and equally measured out sustenance for those who seek sustenance. 10 Then He turned to heaven when it was vapour and said to it and to the earth, "Come willingly or unwillingly." They both said, "We come willingly," 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 If even then they turn away, tell them: "I forewarn you of a terrible punishment like the thunderbolt that fell upon the 'Ad and Thamud." 13 Behold, the messengers came to them, from before them and behind them, (preaching): "Serve none but Allah." They said, "If our Lord had so pleased, He would certainly have sent down angels (to preach). Now we reject your mission (altogether)." 14 As for Ad, they waxed proud in the land without justification and said: “Who is greater than we in strength?” Did they not see that Allah, Who created them, is greater in strength than they? They continued to deny Our Signs, 15 So We sent against them a furious Wind through days of disaster, that We might give them a taste of a Penalty of humiliation in this life; but the Penalty of a Hereafter will be more humiliating still: and they will find no help. 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
