۞ Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds. 9 'And He set therein firm mountains over it, and He blessed it, and He ordained therein its diverse sustenance in four days, 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 ordained them seven heavens in two periods, and revealed in every heaven its affair; and We adorned the lower heaven with brilliant stars and (made it) to guard; that is the decree of the Mighty, 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 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 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 delivered those who believed and were godfearing. 18
