۞ Say “What! You disbelieve in Him Who created the earth in two days, and you appoint equals to Him? He is the Lord Of The Creation!” 9 He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four Days equal (i.e. all these four 'days' were equal in the length of time), for all those who ask (about its creation). 10 He established His dominance over the sky, which (for that time) was like smoke. Then He told the heavens and the earth, "Take your shape either willingly or by force" They said, "We willingly obey". 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 Then if they turn away say, “I warn you of a thunderbolt like the thunderbolt which came upon A’ad and Thamud.” 13 Recall what time the apostles came unto them from before them and behind them, saying: worship none save Allah. They said: had our Lord listed, He surely would have sent down angels, so verily in that wherewith ye have been sent we are disbelievers 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 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. 18
