۞ SAY: "Would you indeed deny Him who has created the earth in two aeons? And do you claim that there is any power that could rival Him, the Sustainer of all the worlds?" 9 He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four Days, alike for (all) 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 So He ordained them seven heavens in two periods, and revealed in every heaven its affair; and We adorned the lower heaven with brilliant stars and (made it) to guard; that is the decree of the Mighty, the Knowing. 12 If they turn away, then say, "I warn you of a lightning-bolt like the one which struck the 'Ad and the Thamud: 13 When their Messengers came to them from before them and behind them, (saying): 'Worship none except Allah' they answered: 'Had it been the will of our Lord, He would have sent down angels. So we disbelieve in the Message with which you were sent' 14 So regarding the A’ad, they were haughty in the land without right, and they said, “Who is more powerful than us?” Did they not realise that Allah, Who created them, is more powerful than them? And they used to deny Our signs. 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 And regarding the Thamud, We showed them the right path – so they chose to be blind above being guided, therefore the thunderbolt of the disgraceful punishment overcame them – the recompense of their deeds. 17 And We delivered those who believed and had been fearing. 18
