۞ Say, "Do you really disbelieve in the One Who created the earth in two days? Do you consider things equal to Him? He is the Lord of the Universe. 9 And in it He placed mountains as anchors from above it, and blessings in it, and appointed the sustenance for those who dwell in it – all this in four days; a proper answer to those who question. 10 Then He willed to the heaven when it was smoke, and to it and the earth He said: 'Come willingly, or unwillingly' 'We come willingly' they answered. 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 But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] 'Aad and 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 So regarding the A’ad, they were haughty in the land without right, and they said, “Who is more powerful than us?” Did they not realise that Allah, Who created them, is more powerful than them? And they used to deny 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 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 And We delivered those who believed and had been fearing. 18
