۞ Tell them, (O Prophet): “Do you indeed disbelieve in Him and assign compeers to Him Who created the earth in two days? He is the Lord of all beings of the Universe. 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 Then He created several skies in two spans, and ingrained in each sky its function, decking the nearest heaven with lamps, and guarded it. This has been determined by the mighty and all-knowing. 12 But if they turn away, tell them: “I warn you against a sudden scourge like that which struck Ad and Thamud.” 13 Behold, the messengers came to them, from before them and behind them, (preaching): "Serve none but Allah." They said, "If our Lord had so pleased, He would certainly have sent down angels (to preach). Now we reject your mission (altogether)." 14 As for the tribe of 'Ad, they behaved arrogantly in the land without any justification and said, "Who is mightier than we in power?" Did they not see that God, who created them, was mightier than they in power? Still 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 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
