۞ 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 And He made in it mountains above its surface, and He blessed therein and made therein its foods, in four periods: alike for the seekers. 10 Then turned He to the heaven when it was smoke, and said unto it and unto the earth: Come both of you, willingly or loth. They said: We come, obedient. 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 And We adorned the lower heaven with lamps, and to reserve; that is the ordaining of the All-mighty, the All-knowing. But if they turn away, then say, 'I warn you of a thunderbolt like to the thunderbolt of Ad and Thamood.' 13 When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah" They said: "If our Lord had so willed, He would surely have sent down the angels. So indeed! We disbelieve in that with which you have been sent." 14 As for the tribe of 'Aad - they grew stiff-necked on the earth without justification, and said: who is mightier than we in strength? Saw they not that Allah who created them, He was Mightier than they in strength? And Our signs they were wont to gainsay. 15 So We sent against them a furious Wind through days of disaster, that We might give them a taste of a Penalty of humiliation in this life; but the Penalty of a Hereafter will be more humiliating still: and they will find no help. 16 And as for Thamud, We showed and made clear to them the Path of Truth (Islamic Monotheism) through Our Messenger, (i.e. showed them the way of success), but they preferred blindness to guidance, so the Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) of disgracing torment seized them, because of what they used to earn. 17 Yet We delivered those who believed and were God-fearing. 18
