۞ Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds. 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 lifted Himself to heaven when it was smoke, and said to it and to the earth, "Come willingly, or unwillingly!" They said, "We come willingly." 11 So He determined them as seven heavens in two days, and revealed its commandment in every heaven.' 12 And We adorned the lower heaven with lamps, and to reserve; that is the ordaining of the All-mighty, the All-knowing. But if they turn away, then say, 'I warn you of a thunderbolt like to the thunderbolt of Ad and Thamood.' 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 Then as to Ad, they were unjustly proud in the land, and they said: Who is mightier in strength than we? Did they not see that Allah Who created them was mightier than they in strength, and they denied Our communications? 15 So We let loose on them a violent wind for several days of distress to make them taste a most disgraceful punishment here in this world, and far more shameful will be the punishment in the Hereafter, and there will be no succour for them. 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 Yet We delivered those who believed and were God-fearing. 18
