۞ Say: "Do you refuse to believe in Him who created the earth in two spans of time, and set up compeers to Him, the Lord of all the worlds? 9 'And He set therein firm mountains over it, and He blessed it, and He ordained therein its diverse sustenance in four days, equal to those who ask.' 10 Then He turned to the heaven while it was all smoke. He said to the heaven and the earth: “Come (into being), willingly or unwillingly.” They said: “Here we come (into being) in willing obeisance.” 11 In two days He determined them seven heavens, and He revealed to each heaven its commands. We decorated the lowest heaven with lamps and preserve them. Such is the decree of the Almighty, the Knower. 12 But if they turn away, say thou: "I have warned you of a stunning Punishment (as of thunder and lightning) like that which (overtook) the 'Ad and the Thamud!" 13 When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah" They said: "If our Lord had so willed, He would surely have sent down the angels. So indeed! We disbelieve in that with which you have been sent." 14 Then as to Ad, they were unjustly proud in the land, and they said: Who is mightier in strength than we? Did they not see that Allah Who created them was mightier than they in strength, and they denied Our communications? 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 for the (tribe of) Thamud, We tried to guide them, but they preferred blindness to guidance; then they were seized by the torment of a humiliating punishment as requital for their misdeeds; 17 We only rescued the believers who had fear of God. 18
