۞ Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is 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 lifted Himself to heaven when it was smoke, and said to it and to the earth, "Come willingly, or unwillingly!" They said, "We come willingly." 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 If they ignore (your message), tell them, "I have warned you against a destructive blast of sound like that which struck the people of `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 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 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 As for Thamud, We bestowed guidance upon them, but they preferred to remain blind rather than be guided. At last a humiliating scourge overtook them on account of their misdeeds. 17 And We delivered those who believed and were godfearing. 18
