۞ 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 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 willed to the heaven when it was smoke, and to it and the earth He said: 'Come willingly, or unwillingly' 'We come willingly' they answered. 11 Then He ordained them seven heavens in two Days and inspired in each heaven its mandate; and We decked the nether heaven with lamps, and rendered it inviolable. That is the measuring of the Mighty, the Knower. 12 But if they turn away, then say: I warn you of a thunderbolt like the thunderbolt (which fell of old upon the tribes) of A'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 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 So We sent on them a furious wind in unlucky days, that We may make them taste the chastisement of abasement in this world's life; and certainly the chastisement of the hereafter is much more abasing, and they shall not be helped. 16 As for the Thamud We offered them Our guidance, but they preferred blindness to guidance. So the lightning-bolt of the punishment of humiliation seized them on account of their misdeeds. 17 And We rescued those who accepted faith and were pious. 18
