۞ 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 firm mountains on top (of the earth) and He blessed it. And in four days He ordained in it many provisions, equal to those who ask. 10 Then He lifted Himself to heaven when it was smoke, and said to it and to the earth, "Come willingly, or unwillingly!" They said, "We come willingly." 11 He then established them into seven heavens in two days, and to each heaven He sent the command of its affairs; and We decorated the lower heaven with lamps; and for its protection; this is the command set by the Most Honourable, the All Knowing. 12 If they turn away, then say, "I warn you of a lightning-bolt like the one which struck the 'Ad and the Thamud: 13 When their Messengers came to them from before them and behind them, (saying): 'Worship none except Allah' they answered: 'Had it been the will of our Lord, He would have sent down angels. So we disbelieve in the Message with which you were sent' 14 Now as for [the tribe of] Ad, they walked arrogantly on earth, [offending] against all right, and saying, "Who could have a power greater than ours?" Why - were they, then, not aware that God, who created them, had a power greater than theirs? But they went on rejecting Our messages; 15 and thereupon We let loose upon them a storm wind raging through days of misfortune, so as to give them, in the life of this world, a foretaste of suffering through humiliation: but [their] suffering in the life to come will be far more humiliating, and they will have none to succour them. 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
