۞ 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 For He [it is who, after creating the earth,] placed firm mountains on it, [towering] above its surface, and bestowed [so many] blessings on it, and equitably apportioned its means of subsistence to all who would seek it: [and all this He created] in four aeons. 10 Then turned He to the heaven when it was smoke, and said unto it and unto the earth: Come both of you, willingly or loth. They said: We come, obedient. 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 BUT IF they turn away, say: "I warn you of [the coming of] a thunderbolt of punishment like the thunderbolt [that fell upon the tribes] of Ad and Thamud!" 13 when the messengers came to them from before them and behind them, saying, 'Worship none but God!" They said, "If our Lord had willed, He would have sent down angels [to us]. Therefore, we shall never believe in your message.'" 14 As for A'ad, they were arrogant in the land without right, and they said: Who is mightier than us in power? Could they not see that Allah Who created them, He was mightier than them in power? And they denied Our revelations. 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 And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn. 17 And We delivered those who believed and used to keep their duty to Allah. 18
