۞ Say: "Do you refuse to believe in Him who created the earth in two spans of time, and set up compeers to Him, the Lord of all 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 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 But if they turn away, say: 'I have given you warning of a thunderbolt similar to that which overtook Aad and Thamood' 13 Their apostles came to them one after the other (saying): "Do not worship any one but God." They said: "If our Lord had pleased He would have sent the angels down. We reject what is sent with you." 14 As for Ad, they waxed proud in the land without justification and said: “Who is greater than we in strength?” Did they not see that Allah, Who created them, is greater in strength than they? They continued to deny Our Signs, 15 So We sent upon them a screaming wind during days of misfortune to make them taste the punishment of disgrace in the worldly life; but the punishment of the Hereafter is more disgracing, and they will not 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 And We delivered those who believed and used to keep their duty to Allah. 18
