۞ Say: What! do you indeed disbelieve in Him Who created the earth in two periods, and do you set up equals with Him? That is the Lord of the Worlds. 9 He placed firm mountains on the earth, and blessed it. He measured out its means of sustenance all in four Days; this is for those who ask for it. 10 Moreover He comprehended in His design the sky, and it had been (as) smoke: He said to it and to the earth: "Come ye together, willingly or unwillingly." They said: "We do come (together), in willing obedience." 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 But if they turn away, then say: I warn you of a thunderbolt like the thunderbolt (which fell of old upon the tribes) of A'ad and Thamud; 13 Lo! There came unto them [God's] apostles, speaking of what lay open before them and what was [still] beyond their ken, [and calling unto them,] "Worship none but God!" They answered: "If our Sustainer had willed [us to believe in what you say,] He would have sent down angels [as His message-bearers]. As it is, behold, we deny that there is any truth in what you [claim to] 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 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 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 We only rescued the believers who had fear of God. 18
