۞ 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 placed on the earth firmly set mountains over its surface, and He blessed it and determined therein its [creatures'] sustenance in four days without distinction - for [the information] of those who ask. 10 Then He turned to heaven when it was vapour and said to it and to the earth, "Come willingly or unwillingly." They both said, "We come willingly," 11 Then He created several skies in two spans, and ingrained in each sky its function, decking the nearest heaven with lamps, and guarded it. This has been determined by the mighty and 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 the Messengers (of Allah) came to them from the front and from the rear, saying: “Do not serve any but Allah”; they said: “Had our Lord so willed, He would have sent down angels. So we deny the Message you have brought.” 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 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 As for the Thamud We offered them Our guidance, but they preferred blindness to guidance. So the lightning-bolt of the punishment of humiliation seized them on account of their misdeeds. 17 And We delivered those who believed and used to keep their duty to Allah. 18
