۞ Say, "Do you indeed disbelieve in He who created the earth in two days and attribute to Him equals? That 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 turned to heaven when it was vapour and said to it and to the earth, "Come 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 aside, then say: I have warned you of a scourge like the scourge of Ad and Samood. 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 As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidences, verses, lessons, revelations, etc.)! 15 We therefore sent a violent thunderstorm towards them in their days of misfortune, in order to make them taste a disgraceful punishment in the life of this world; and indeed the punishment of the Hereafter is more disgracing, and they will not be helped. 16 And as to Samood, We showed them the right way, but they chose error above guidance, so there overtook them the scourge of an abasing chastisement for what they earned. 17 And We rescued those who accepted faith and were pious. 18
