۞ Say: 'What, do you disbelieve in Him who created the earth in two days, and do you set up compeers to Him? That is the Lord of all Being. 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 directed Himself to the heaven while it was smoke and said to it and to the earth, "Come [into being], willingly or by compulsion." They said, "We have come willingly." 11 So He ordained them seven heavens in two periods, and revealed in every heaven its affair; and We adorned the lower heaven with brilliant stars and (made it) to guard; that is the decree of the Mighty, the Knowing. 12 But if they turn away, say: 'I have given you warning of a thunderbolt similar to that which overtook Aad and Thamood' 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 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 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 As to the Thamud, We gave them Guidance, but they preferred blindness (of heart) to Guidance: so the stunning Punishment of humiliation seized them, because of what they had earned. 17 But We delivered those who believed and practised righteousness. 18
