۞ Say (O Muhammad SAW): "Do you verily disbelieve in Him Who created the earth in two Days and you set up rivals (in worship) with Him? That is the Lord of the 'Alamin (mankind, jinns and all that exists). 9 'And He set therein firm mountains over it, and He blessed it, and He ordained therein its diverse sustenance in four days, 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 So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge. 12 But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] 'Aad and 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 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 (offered) them Our Guidance, but they preferred blindness to guidance. So a thunderbolt of the humiliating punishment seized them because of what they had earned; 17 and We saved [only] those who had attained to faith and were conscious of Us. 18
