۞ Say: 'What, do you disbelieve in Him who created the earth in two days, and do you set up compeers to Him? That is the Lord of all Being. 9 And He made in it mountains above its surface, and He blessed therein and made therein its foods, in four periods: alike for the seekers. 10 Then He willed to the heaven when it was smoke, and to it and the earth He said: 'Come willingly, or unwillingly' 'We come willingly' they answered. 11 He formed the seven heavens in two days and revealed to each one its task. He decked the sky above the earth with torches and protected it from (intruders).. Such is the design of the Majestic and All-knowing God". 12 But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] 'Aad 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 Now as for [the tribe of] Ad, they walked arrogantly on earth, [offending] against all right, and saying, "Who could have a power greater than ours?" Why - were they, then, not aware that God, who created them, had a power greater than theirs? But they went on rejecting Our messages; 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 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 delivered those who believed and used to keep their duty to Allah. 18
