۞ Say: 'Do you disbelieve in Him who created the earth in two days? And do you set up equals with Him? He is the Lord of the Worlds' 9 He placed firm mountains on the earth, and blessed it. He measured out its means of sustenance all in four Days; this is for those who ask for it. 10 Then He directed Himself to the heaven while it was smoke and said to it and to the earth, "Come [into being], willingly or by compulsion." They said, "We have come willingly." 11 He formed the seven heavens in two days and revealed to each one its task. He decked the sky above the earth with torches and protected it from (intruders).. Such is the design of the Majestic and All-knowing God". 12 But if they turn aside, then say: I have warned you of a scourge like the scourge of Ad and Samood. 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 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 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 saved [only] those who had attained to faith and were conscious of Us. 18
