۞ 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 In four days He placed the mountains on it, blessed it, and equally measured out sustenance for those who seek sustenance. 10 Then He turned to heaven when it was vapour and said to it and to the earth, "Come willingly or unwillingly." They both said, "We come willingly," 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 Then if they turn away say, “I warn you of a thunderbolt like the thunderbolt which came upon A’ad and Thamud.” 13 Their apostles came to them one after the other (saying): "Do not worship any one but God." They said: "If our Lord had pleased He would have sent the angels down. We reject what is sent with you." 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 the Thamud We offered them Our guidance, but they preferred blindness to guidance. So the lightning-bolt of the punishment of humiliation seized them on account of their misdeeds. 17 And We delivered those who believed and used to keep their duty to Allah. 18
