۞ Say, "Do you really disbelieve in the One Who created the earth in two days? Do you consider things equal to Him? He is the Lord of the Universe. 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 lifted Himself to heaven when it was smoke, and said to it and to the earth, "Come willingly, or unwillingly!" They said, "We come willingly." 11 So He determined them as seven heavens in two days, and revealed its commandment in every heaven.' 12 If they turn away, then say, "I warn you of a lightning-bolt like the one which struck the 'Ad and the Thamud: 13 When the Messengers (of Allah) came to them from the front and from the rear, saying: “Do not serve any but Allah”; they said: “Had our Lord so willed, He would have sent down angels. So we deny the Message you have brought.” 14 Now the 'Ad behaved arrogantly through the land, against (all) truth and reason, and said: "Who is superior to us in strength?" What! did they not see that Allah, Who created them, was superior to them in strength? But they continued to reject Our Signs! 15 Therefor We let loose on them a raging wind in evil days, that We might make them taste the torment of disgrace in the life of the world. And verily the doom of the Hereafter will be more shameful, and they will not be helped. 16 And as for Thamud, We guided them, but they preferred blindness over guidance, so the thunderbolt of humiliating punishment seized them for what they used to earn. 17 But We delivered those who believed and practised righteousness. 18
