۞ 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 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 Then He directed Himself to the heaven and it is a vapor, so He said to it and to the earth: Come both, willingly or unwillingly. They both said: We come willingly. 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 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 the 'Ad behaved arrogantly through the land, against (all) truth and reason, and said: "Who is superior to us in strength?" What! did they not see that Allah, Who created them, was superior to them in strength? But they continued to reject Our Signs! 15 So We sent upon them a screaming wind during days of misfortune to make them taste the punishment of disgrace in the worldly life; but the punishment of the Hereafter is more disgracing, and they will not be helped. 16 And regarding the Thamud, We showed them the right path – so they chose to be blind above being guided, therefore the thunderbolt of the disgraceful punishment overcame them – the recompense of their deeds. 17 And We saved those who believed and used to fear Allah, keep their duty to Him and avoid evil. 18
