۞ SAY: "Would you indeed deny Him who has created the earth in two aeons? And do you claim that there is any power that could rival Him, the Sustainer of all the worlds?" 9 And in it He placed mountains as anchors from above it, and blessings in it, and appointed the sustenance for those who dwell in it – all this in four days; a proper answer to those who question. 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 And We adorned the lower heaven with lamps, and to reserve; that is the ordaining of the All-mighty, the All-knowing. But if they turn away, then say, 'I warn you of a thunderbolt like to the thunderbolt of Ad and Thamood.' 13 Recall what time the apostles came unto them from before them and behind them, saying: worship none save Allah. They said: had our Lord listed, He surely would have sent down angels, so verily in that wherewith ye have been sent we are disbelievers altogether. 14 So those who were 'Ad turned insolent unjustly in the land, and said: "Who is stronger than us?" Did they not see that God who created them was greater far in power than they? Yet they refused to believe Our signs. 15 and thereupon We let loose upon them a storm wind raging through days of misfortune, so as to give them, in the life of this world, a foretaste of suffering through humiliation: but [their] suffering in the life to come will be far more humiliating, and they will have none to succour them. 16 As for Thamood, We (offered) them Our Guidance, but they preferred blindness to guidance. So a thunderbolt of the humiliating punishment seized them because of what they had earned; 17 and We saved [only] those who had attained to faith and were conscious of Us. 18
