۞ Say thou: are ye indeed those who disbelieve in Him who hath created the earth in two days, and set up unto Him peers? That is the Lord of the worlds. 9 He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four Days equal (i.e. all these four 'days' were equal in the length of time), for all those who ask (about its creation). 10 He established His dominance over the sky, which (for that time) was like smoke. Then He told the heavens and the earth, "Take your shape either willingly or by force" They said, "We willingly obey". 11 Then He made them seven heavens in two days and revealed to each heaven its law. And We adorned the lower heaven with lamps, and firmly secured it. All this is the firm plan of the All-Mighty, 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 Messengers from all sides came to them saying, "Do not worship anything besides God, " they said, "Had our Lord wanted, He would have sent us angelic Messengers. We do not believe in your message". 14 The people of Ad unjustly sought dominance on earth saying, "Who is more powerful than us?" Did they not consider that God created them and that He is more powerful than they were?" They rejected Our revelations. 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 Thamud, We guided them, but they preferred blindness over guidance, so the thunderbolt of humiliating punishment seized them for what they used to earn. 17 We only rescued the believers who had fear of God. 18
