۞ 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 He made in it mountains above its surface, and He blessed therein and made therein its foods, in four periods: alike for the seekers. 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 and in two Days He formed seven heavens, and revealed to each heaven its functions; and We adorned the lower heaven with brilliant lamps [stars] and guarded it. That is the decree of the Almighty, the All Knowing. 12 If they ignore (your message), tell them, "I have warned you against a destructive blast of sound like that which struck the people of `Ad and Thamud. 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 A'ad, they were arrogant in the land without right, and they said: Who is mightier than us in power? Could they not see that Allah Who created them, He was mightier than them in power? And they denied 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 (offered) them Our Guidance, but they preferred blindness to guidance. So a thunderbolt of the humiliating punishment seized them because of what they had earned; 17 We saved those who had attained to faith and were God-fearing. 18
