Here Allah tells us that He has decreed and it is written in Al-Lawh Al-Mahfuz (The Preserved Tablet) which is with Him, that there is no town that He will not destroy by wiping out all its people or by punishing them,

[عَذَاباً شَدِيداً]

(with a severe torment.) either by killing them or sending calamities upon them as He wills. This will be because of their sins, as Allah says of the past nations:

[وَمَا ظَلَمْنَـهُمْ وَلَـكِن ظَلَمُواْ أَنفُسَهُمْ]

(We wronged them not, but they wronged themselves.) [11:101]

[فَذَاقَتْ وَبَالَ أَمْرِهَا وَكَانَ عَـقِبَةُ أَمْرِهَا خُسْراً ]

(So it tasted the evil result of its affair (disbelief), and the consequence of its affair (disbelief) was loss.) [65:9]

[وَكَأِيِّن مِّن قَرْيَةٍ عَتَتْ عَنْ أَمْرِ رَبِّهَا وَرُسُلِهِ]

(And many a town (population) revolted against the command of its Lord and His Messengers;) [65:8] and many Ayat.

[وَمَا مَنَعَنَآ أَن نُّرْسِلَ بِالاٌّيَـتِ إِلاَّ أَن كَذَّبَ بِهَا الاٌّوَّلُونَ وَءَاتَيْنَا ثَمُودَ النَّاقَةَ مُبْصِرَةً فَظَلَمُواْ بِهَا وَمَا نُرْسِلُ بِالاٌّيَـتِ إِلاَّ تَخْوِيفًا ]

(59. And nothing stops Us from sending the Ayat but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to make them afraid (of destruction).)
