۞ 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 set firm mountains on top (of the earth) and He blessed it. And in four days He ordained in it many provisions, equal to those who ask. 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 And He [it is who] decreed that they become seven heavens in two aeons, and imparted unto each heaven its function. And We adorned the skies nearest to the earth with lights, and made them secure: such is the ordaining of the Almighty, the All-Knowing. 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 When their Messengers came to them from before them and behind them, (saying): 'Worship none except Allah' they answered: 'Had it been the will of our Lord, He would have sent down angels. So we disbelieve in the Message with which you were sent' 14 As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidences, verses, lessons, revelations, etc.)! 15 So We sent against them a furious Wind through days of disaster, that We might give them a taste of a Penalty of humiliation in this life; but the Penalty of a Hereafter will be more humiliating still: and they will find no help. 16 And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn. 17 But We delivered those who believed and practised righteousness. 18
