۞ 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 (After creating the earth) He set up firm mountains on it, blessed it, and provided it with sustenance in proportion to the needs of all who seek (sustenance). All this was done in four days. 10 And He [it is who] applied His design to the skies, which were [yet but] smoke; and He [it is who] said to them and to the earth, "Come [into being,] both of you, willingly or unwillingly!" - to which both responded, "We do come in obedience." 11 So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge. 12 And We adorned the lower heaven with lamps, and to reserve; that is the ordaining of the All-mighty, the All-knowing. But if they turn away, then say, 'I warn you of a thunderbolt like to the thunderbolt of Ad and Thamood.' 13 when the messengers came to them from before them and behind them, saying, 'Worship none but God!" They said, "If our Lord had willed, He would have sent down angels [to us]. Therefore, we shall never believe in your message.'" 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 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 As for the (tribe of) Thamud, We tried to guide them, but they preferred blindness to guidance; then they were seized by the torment of a humiliating punishment as requital for their misdeeds; 17 And We delivered those who believed and were godfearing. 18
