۞ Say, "Do you really disbelieve in the One Who created the earth in two days? Do you consider things equal to Him? He is the Lord of the Universe. 9 He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measure therein all things to give them nourishment in due proportion, in four Days, in accordance with (the needs of) those who seek (Sustenance). 10 Then He turned to the heaven while it was all smoke. He said to the heaven and the earth: “Come (into being), willingly or unwillingly.” They said: “Here we come (into being) in willing obeisance.” 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 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 Noble Messengers approached them from front and from behind saying, "Do not worship any one except Allah"; they said, "If our Lord willed, He would surely have sent down angels – we therefore deny whatever you have been sent with.” 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 We sent upon them a violent wind during a few ill-fated days to make them suffer a disgraceful torment in this life. Their torment in the life to come will be even more disgraceful and they will not receive any help. 16 We sent guidance to the people of Thamud but they preferred blindness to guidance so a humiliating blast of torment struck them for their evil deeds. 17 We saved those who had attained to faith and were God-fearing. 18
