۞ Say: 'Do you disbelieve in Him who created the earth in two days? And do you set up equals with Him? He is the Lord of the Worlds' 9 In four days He placed the mountains on it, blessed it, and equally measured out sustenance for those who seek sustenance. 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, 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 messengers came unto them from before them and behind them, saying: Worship none but Allah! they said: If our Lord had willed, He surely would have sent down angels (unto us), so lo! we are disbelievers in that wherewith ye have been sent. 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 sent upon them a violent wind during a few ill-fated days to make them suffer a disgraceful torment in this life. Their torment in the life to come will be even more disgraceful and they will not receive any help. 16 And as for the tribe of the Thamud We guided them but they preferred blindness to the guidance, wherefore the bolt of the torment of abjection laid hold of them because of that which they had been earning. 17 and We saved [only] those who had attained to faith and were conscious of Us. 18
