۞ Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds. 9 He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measure therein all things to give them nourishment in due proportion, in four Days, in accordance with (the needs of) 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 Then He decreed them as seven heavens in two days, and revealed unto each heaven the command thereof; and We bedecked the nether heaven with lamps and placed therein a guard. That is the ordinance of the Mighty, the Knower. 12 But if they turn away, say: 'I have given you warning of a thunderbolt similar to that which overtook Aad and Thamood' 13 Behold, the messengers came to them, from before them and behind them, (preaching): "Serve none but Allah." They said, "If our Lord had so pleased, He would certainly have sent down angels (to preach). Now we reject your mission (altogether)." 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 Thamood, We guided them, but they preferred blindness above guidance, so the thunderbolt of the chastisement of humiliation seized them for that they were earning. 17 And We delivered those who believed and guarded (against evil). 18
