۞ 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 And He placed therein mountains firmly rooted rising above it, and blessed it, and ordained therein the sustenance thereof, all this in four days, complete; this for the inquirers. 10 Then He willed to the heaven when it was smoke, and to it and the earth He said: 'Come willingly, or unwillingly' 'We come willingly' they answered. 11 He then established them into seven heavens in two days, and to each heaven He sent the command of its affairs; and We decorated the lower heaven with lamps; and for its protection; this is the command set by the Most Honourable, 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 Their apostles came to them one after the other (saying): "Do not worship any one but God." They said: "If our Lord had pleased He would have sent the angels down. We reject what is sent with you." 14 So those who were 'Ad turned insolent unjustly in the land, and said: "Who is stronger than us?" Did they not see that God who created them was greater far in power than they? Yet they refused to believe Our signs. 15 whereupon We sent upon them a fierce wind on inauspicious days that We might make them taste a degrading chastisement in the life of this world. And surely the chastisement of the Hereafter is even more degrading. There will be none to help them there. 16 And as to Samood, We showed them the right way, but they chose error above guidance, so there overtook them the scourge of an abasing chastisement for what they earned. 17 And We delivered those who believed and guarded (against evil). 18
