۞ Say “What! You disbelieve in Him Who created the earth in two days, and you appoint equals to Him? He is the Lord Of The Creation!” 9 And in it He placed mountains as anchors from above it, and blessings in it, and appointed the sustenance for those who dwell in it – all this in four days; a proper answer to those who question. 10 Then He Istawa (rose over) towards the heaven when it was smoke, and said to it and to the earth: "Come both of you willingly or unwillingly." They both said: "We come, willingly." 11 He then established them into seven heavens in two days, and to each heaven He sent the command of its affairs; and We decorated the lower heaven with lamps; and for its protection; this is the command set by the Most Honourable, the All Knowing. 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 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 '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 whereupon We sent upon them a fierce wind on inauspicious days that We might make them taste a degrading chastisement in the life of this world. And surely the chastisement of the Hereafter is even more degrading. There will be none to help them there. 16 As for the (tribe of) Thamud, We tried to guide them, but they preferred blindness to guidance; then they were seized by the torment of a humiliating punishment as requital for their misdeeds; 17 And We saved those who believed and used to fear Allah. 18
