۞ Say “What! You disbelieve in Him Who created the earth in two days, and you appoint equals to Him? He is the Lord Of The Creation!” 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 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 Then He decreed them as seven heavens in two days, and revealed unto each heaven the command thereof; and We bedecked the nether heaven with lamps and placed therein a guard. That is the ordinance of the Mighty, the Knower. 12 If they ignore (your message), tell them, "I have warned you against a destructive blast of sound like that which struck the people of `Ad and Thamud. 13 When the Messengers came unto them from before them and from behind them, saying, 'Serve none but God,' they said, 'Had our Lord willed, surely He would have sent down angels; so we disbelieve in the Message you were sent with.' 14 So regarding the A’ad, they were haughty in the land without right, and they said, “Who is more powerful than us?” Did they not realise that Allah, Who created them, is more powerful than them? And they used to deny Our signs. 15 So We sent upon them furious wind in days of evil omen (for them) that We might give them a taste of disgracing torment in this present worldly life, but surely the torment of the Hereafter will be more disgracing, and they will never be helped. 16 And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn. 17 Yet We delivered those who believed and were God-fearing. 18
