۞ Say thou: are ye indeed those who disbelieve in Him who hath created the earth in two days, and set up unto Him peers? That is the Lord of the worlds. 9 He placed firm stabilisers rising above its surface, blessed it with plenty and growth, and ingrained the means of growing its food within it, sufficient for all seekers, in four spans. 10 And He [it is who] applied His design to the skies, which were [yet but] smoke; and He [it is who] said to them and to the earth, "Come [into being,] both of you, willingly or unwillingly!" - to which both responded, "We do come in obedience." 11 Then He decreed them as seven heavens in two days, and revealed unto each heaven the command thereof; and We bedecked the nether heaven with lamps and placed therein a guard. That is the ordinance of the Mighty, the Knower. 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 their apostles came to them from before them and from behind them, saying, Serve nothing but Allah, they said: If our Lord had pleased He would certainly have sent down angels, so we are surely unbelievers in that with which you are sent. 14 So those who were 'Ad turned insolent unjustly in the land, and said: "Who is stronger than us?" Did they not see that God who created them was greater far in power than they? Yet they refused to believe Our signs. 15 Then, on the ominous days, We loosed against them a howling wind that We might let them taste the punishment of humiliation in this life; but more humiliating will be the punishment of the Everlasting Life and they will not be helped. 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 And We rescued those who accepted faith and were pious. 18
