۞ 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 set firm mountains on top (of the earth) and He blessed it. And in four days He ordained in it many provisions, equal to those who ask. 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 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 Messengers came to them from before them and behind them, (saying): 'Worship none except Allah' they answered: 'Had it been the will of our Lord, He would have sent down angels. So we disbelieve in the Message with which you were sent' 14 As for Aad, they behaved proudly in the earth without right. 'Who is stronger than us?' they would say. Could they not see that Allah, who created them, is stronger than they? But they disbelieved Our signs. 15 Then We loosed against them a wind clamorous in days of ill fortune, that We might let them taste the chastisement of degradation in the present life; and the chastisement of the world to come is even more degrading, and they shall not be helped. 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 saved those who believed and used to fear Allah. 18
