۞ 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 '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 directed Himself to the heaven and it is a vapor, so He said to it and to the earth: Come both, willingly or unwillingly. They both said: We come willingly. 11 and in two Days He formed seven heavens, and revealed to each heaven its functions; and We adorned the lower heaven with brilliant lamps [stars] and guarded it. That is the decree of the Almighty, the All Knowing. 12 If they turn away, then say, "I warn you of a lightning-bolt like the one which struck the 'Ad and the Thamud: 13 When their messengers came unto them from before them and behind them, saying: Worship none but Allah! they said: If our Lord had willed, He surely would have sent down angels (unto us), so lo! we are disbelievers in that wherewith ye have been sent. 14 Now the 'Ad behaved arrogantly through the land, against (all) truth and reason, and said: "Who is superior to us in strength?" What! did they not see that Allah, Who created them, was superior to them in strength? But they continued to reject Our Signs! 15 Then, on the ominous days, We loosed against them a howling wind that We might let them taste the punishment of humiliation in this life; but more humiliating will be the punishment of the Everlasting Life and they will not be helped. 16 And as for [the tribe of] Thamud, We offered them guidance, but they chose blindness in preference to guidance: and so the thunderbolt of shameful suffering fell upon them as an outcome of all [the evil] that they had wrought; 17 and We saved those who believed and feared Allah. 18
