۞ 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 He placed firm stabilisers rising above its surface, blessed it with plenty and growth, and ingrained the means of growing its food within it, sufficient for all seekers, in four spans. 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 Then He ordained them seven heavens in two Days and inspired in each heaven its mandate; and We decked the nether heaven with lamps, and rendered it inviolable. That is the measuring of the Mighty, the Knower. 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 Lo! There came unto them [God's] apostles, speaking of what lay open before them and what was [still] beyond their ken, [and calling unto them,] "Worship none but God!" They answered: "If our Sustainer had willed [us to believe in what you say,] He would have sent down angels [as His message-bearers]. As it is, behold, we deny that there is any truth in what you [claim to] have been sent with!" 14 As for Aad, they behaved proudly in the earth without right. 'Who is stronger than us?' they would say. Could they not see that Allah, who created them, is stronger than they? But they disbelieved Our signs. 15 So We sent on them a furious wind in unlucky days, that We may make them taste the chastisement of abasement in this world's life; and certainly the chastisement of the hereafter is much more abasing, and they shall not be helped. 16 And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn. 17 But We delivered those who believed and practised righteousness. 18
