۞ Say thou: are ye indeed those who disbelieve in Him who hath created the earth in two days, and set up unto Him peers? That is the Lord of the worlds. 9 And He made in it mountains above its surface, and He blessed therein and made therein its foods, in four periods: alike for the seekers. 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 formed the seven heavens in two days and revealed to each one its task. He decked the sky above the earth with torches and protected it from (intruders).. Such is the design of the Majestic and All-knowing God". 12 BUT IF they turn away, say: "I warn you of [the coming of] a thunderbolt of punishment like the thunderbolt [that fell upon the tribes] of Ad and Thamud!" 13 When Messengers from all sides came to them saying, "Do not worship anything besides God, " they said, "Had our Lord wanted, He would have sent us angelic Messengers. We do not believe in your message". 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 Wherefore We sent upon them a raging wind in days inauspicious, that We might make them taste the torment of humiliation in the life of the world; and surely the torment of the Hereafter will be more humiliating, nor will they be succoured. 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 We saved those who had attained to faith and were God-fearing. 18
