۞ 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 (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 turned He to the heaven when it was smoke, and said unto it and unto the earth: Come both of you, willingly or loth. They said: We come, obedient. 11 He formed the seven heavens in two days and revealed to each one its task. He decked the sky above the earth with torches and protected it from (intruders).. Such is the design of the Majestic and All-knowing God". 12 But if they turn aside, then say: I have warned you of a scourge like the scourge of Ad and Samood. 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 Wherefore We sent upon them a raging wind in days inauspicious, that We might make them taste the torment of humiliation in the life of the world; and surely the torment of the Hereafter will be more humiliating, nor will they be succoured. 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 But We delivered those who believed and practised righteousness. 18
