۞ Say, "Do you indeed disbelieve in He who created the earth in two days and attribute to Him equals? That is the Lord of 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 He then inclined towards the heavens and it was smoke – thereupon He said to it and to the earth, “Both of you present yourselves, willingly or with reluctance”; they said, “We present ourselves, with zeal.” 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 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 the Messengers (of Allah) came to them from the front and from the rear, saying: “Do not serve any but Allah”; they said: “Had our Lord so willed, He would have sent down angels. So we deny the Message you have brought.” 14 As for Ad, they waxed proud in the land without justification and said: “Who is greater than we in strength?” Did they not see that Allah, Who created them, is greater in strength than they? They continued to deny Our Signs, 15 and thereupon We let loose upon them a storm wind raging through days of misfortune, so as to give them, in the life of this world, a foretaste of suffering through humiliation: but [their] suffering in the life to come will be far more humiliating, and they will have none to succour them. 16 As to the Thamud, We gave them Guidance, but they preferred blindness (of heart) to Guidance: so the stunning Punishment of humiliation seized them, because of what they had earned. 17 But We saved those who believed and took heed for themselves. 18
