How many populations that insolently opposed the Command of their Lord and of His messengers, did We not then call to account,- to severe account?- and We imposed on them an exemplary Punishment. 8 So it tasted the mischief of its action, and the end of its matter was loss. 9 Allah has prepared for them severe chastisement, therefore be careful of (your duty to) Allah, O men of understanding who believe! Allah has indeed revealed to you a reminder, 10 An Messenger, who rehearses to you the Signs of Allah containing clear explanations, that he may lead forth those who believe and do righteous deeds from the depths of Darkness into Light. And those who believe in Allah and work righteousness, He will admit to Gardens beneath which Rivers flow, to dwell therein for ever: Allah has indeed granted for them a most excellent Provision. 11 It is Allah Who has created seven heavens and of the earth the like thereof (i.e. seven). His Command descends between them (heavens and earth), that you may know that Allah has power over all things, and that Allah surrounds (comprehends) all things in (His) Knowledge. 12
