۞ Tell them, (O Prophet): “Do you indeed disbelieve in Him and assign compeers to Him Who created the earth in two days? He is the Lord of all beings of the Universe. 9 In four days He placed the mountains on it, blessed it, and equally measured out sustenance for those who seek sustenance. 10 Thereafter turned He to the heaven and it was as smoke, and said unto it and unto the earth: come ye twain, willingly or loth. They said: we 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, then say: I warn you of a thunderbolt like the thunderbolt (which fell of old upon the tribes) of A'ad and Thamud; 13 When their apostles came to them from before them and from behind them, saying, Serve nothing but Allah, they said: If our Lord had pleased He would certainly have sent down angels, so we are surely unbelievers in that with which you are sent. 14 Now as for [the tribe of] Ad, they walked arrogantly on earth, [offending] against all right, and saying, "Who could have a power greater than ours?" Why - were they, then, not aware that God, who created them, had a power greater than theirs? But they went on rejecting Our messages; 15 and thereupon We let loose upon them a storm wind raging through days of misfortune, so as to give them, in the life of this world, a foretaste of suffering through humiliation: but [their] suffering in the life to come will be far more humiliating, and they will have none to succour them. 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 And We delivered those who believed and used to keep their duty to Allah. 18
