How many a city turned in disdain from the commandment of its Lord and His Messengers; and then We made with it a terrible reckoning and chastised it with a horrible chastisement. 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 Allah is He Who created seven Firmaments and of the earth a similar number. Through the midst of them (all) descends His Command: that ye may know that Allah has power over all things, and that Allah comprehends, all things in (His) Knowledge. 12
