۞ 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 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 So He determined them as seven heavens in two days, and revealed its commandment in every heaven.' 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 [That occurred] when the messengers had come to them before them and after them, [saying], "Worship not except Allah." They said, "If our Lord had willed, He would have sent down the angels, so indeed we, in that with which you have been sent, are disbelievers." 14 As for the tribe of 'Ad, they behaved arrogantly in the land without any justification and said, "Who is mightier than we in power?" Did they not see that God, who created them, was mightier than they in power? Still they continued to deny 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 Thamud We offered them Our guidance, but they preferred blindness to guidance. So the lightning-bolt of the punishment of humiliation seized them on account of their misdeeds. 17 And We rescued those who accepted faith and were pious. 18
