۞ Say, "What! Do you indeed deny Him who created the earth in two Days [periods] and do you set up equals with Him? He is the Lord of the Universe." 9 He set firm mountains on top (of the earth) and He blessed it. And in four days He ordained in it many provisions, equal to those who ask. 10 Then He turned to the heavens, and it was smoke. So He said to it and the earth: "Come with willing obedience or perforce." They said: "We come willingly." 11 and in two Days He formed seven heavens, and revealed to each heaven its functions; and We adorned the lower heaven with brilliant lamps [stars] and guarded it. That is the decree of the Almighty, the All Knowing. 12 But if they turn away, say: 'I have given you warning of a thunderbolt similar to that which overtook Aad and Thamood' 13 When their messengers came unto them from before them and behind them, saying: Worship none but Allah! they said: If our Lord had willed, He surely would have sent down angels (unto us), so lo! we are disbelievers in that wherewith ye have been sent. 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 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 (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 those who believed and used to fear Allah. 18
