۞ Say, "Do you indeed disbelieve in He who created the earth in two days and attribute to Him equals? That is the Lord of the worlds." 9 He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four Days, alike for (all) who ask; 10 Then He lifted Himself to heaven when it was smoke, and said to it and to the earth, "Come willingly, or unwillingly!" They said, "We come willingly." 11 And He completed them as seven heavens within two days and inspired in each heaven its command. And We adorned the nearest heaven with lamps and as protection. That is the determination of the Exalted in Might, the Knowing. 12 But if they turn aside, then say: I have warned you of a scourge like the scourge of Ad and Samood. 13 when the messengers came to them from before them and behind them, saying, 'Worship none but God!" They said, "If our Lord had willed, He would have sent down angels [to us]. Therefore, we shall never believe in your message.'" 14 The people of Ad unjustly sought dominance on earth saying, "Who is more powerful than us?" Did they not consider that God created them and that He is more powerful than they were?" They rejected Our revelations. 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 As for Thamood, We guided them, but they preferred blindness above guidance, so the thunderbolt of the chastisement of humiliation seized them for that they were earning. 17 And We saved those who believed and used to fear Allah, keep their duty to Him and avoid evil. 18
