۞ 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 established His dominance over the sky, which (for that time) was like smoke. Then He told the heavens and the earth, "Take your shape either willingly or by force" They said, "We willingly obey". 11 So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge. 12 But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] 'Aad and Thamud. 13 When their Noble Messengers approached them from front and from behind saying, "Do not worship any one except Allah"; they said, "If our Lord willed, He would surely have sent down angels – we therefore deny whatever you have been sent with.” 14 The people of Ad unjustly sought dominance on earth saying, "Who is more powerful than us?" Did they not consider that God created them and that He is more powerful than they were?" They rejected Our revelations. 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 for Thamood, We guided them, but they preferred blindness above guidance, so the thunderbolt of the chastisement of humiliation seized them for that they were earning. 17 But We saved those who believed and took heed for themselves. 18
