۞ 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 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 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 And He [it is who] decreed that they become seven heavens in two aeons, and imparted unto each heaven its function. And We adorned the skies nearest to the earth with lights, and made them secure: such is the ordaining of the Almighty, the All-Knowing. 12 Then if they turn away say, “I warn you of a thunderbolt like the thunderbolt which came upon A’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 the tribe of 'Ad, they behaved arrogantly in the land without any justification and said, "Who is mightier than we in power?" Did they not see that God, who created them, was mightier than they in power? Still they continued to deny Our signs, 15 Then, on the ominous days, We loosed against them a howling wind that We might let them taste the punishment of humiliation in this life; but more humiliating will be the punishment of the Everlasting Life and they will not be helped. 16 We sent guidance to the people of Thamud but they preferred blindness to guidance so a humiliating blast of torment struck them for their evil deeds. 17 And We delivered those who believed and had been fearing. 18
