۞ 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 He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four Days, alike for (all) who ask; 10 Then He turned to the heavens, and it was smoke. So He said to it and the earth: "Come with willing obedience or perforce." They said: "We come willingly." 11 And He completed them as seven heavens within two days and inspired in each heaven its command. And We adorned the nearest heaven with lamps and as protection. That is the determination of the Exalted in Might, the 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 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 Ad, they waxed proud in the land without justification and said: “Who is greater than we in strength?” Did they not see that Allah, Who created them, is greater in strength than they? They continued to deny Our Signs, 15 So We sent upon them a screaming wind during days of misfortune to make them taste the punishment of disgrace in the worldly life; but the punishment of the Hereafter is more disgracing, and they will not be helped. 16 We sent guidance to the people of Thamud but they preferred blindness to guidance so a humiliating blast of torment struck them for their evil deeds. 17 We only rescued the believers who had fear of God. 18
