۞ Say (O Muhammad, unto the idolaters): Disbelieve ye verily in Him Who created the earth in two Days, and ascribe ye unto Him rivals? He (and none else) is the Lord of the Worlds. 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 directed Himself to the heaven and it is a vapor, so He said to it and to the earth: Come both, willingly or unwillingly. They both said: We come willingly. 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 away, tell them: “I warn you against a sudden scourge like that which struck Ad and Thamud.” 13 When their Noble Messengers approached them from front and from behind saying, "Do not worship any one except Allah"; they said, "If our Lord willed, He would surely have sent down angels – we therefore deny whatever you have been sent with.” 14 As for Aad, they behaved proudly in the earth without right. 'Who is stronger than us?' they would say. Could they not see that Allah, who created them, is stronger than they? But they disbelieved 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 But We delivered those who believed and practised righteousness. 18
