۞ Say: 'Do you disbelieve in Him who created the earth in two days? And do you set up equals with Him? He is the Lord of the Worlds' 9 He placed firm mountains on the earth, and blessed it. He measured out its means of sustenance all in four Days; this is for those who ask for it. 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 determined them as seven heavens in two days, and revealed its commandment in every heaven.' 12 But if they turn aside, then say: I have warned you of a scourge like the scourge of Ad and Samood. 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 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 Then We loosed against them a wind clamorous in days of ill fortune, that We might let them taste the chastisement of degradation in the present life; and the chastisement of the world to come is even more degrading, and they shall not be helped. 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 were godfearing. 18
