The Destruction or Torment of all Disbelieving Towns before the Hour begins

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,

﴿ عَذَابً۬ا شَدِيدً۬ا‌ۚ ﴾

(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 ظَلَمۡنَـٰهُمۡ وَلَـٰكِن ظَلَمُوٓاْ أَنفُسَہُمۡ‌ۖ ﴾

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

﴿ فَذَاقَتۡ وَبَالَ أَمۡرِهَا وَكَانَ عَـٰقِبَةُ أَمۡرِهَا خُسۡرًا ﴾

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

﴿ وَكَأَيِّن مِّن قَرۡيَةٍ عَتَتۡ عَنۡ أَمۡرِ رَبِّہَا وَرُسُلِهِۦ ﴾

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

﴿ وَمَا مَنَعَنَآ أَن نُّرۡسِلَ بِٱلۡأَيَـٰتِ إِلَّآ أَن ڪَذَّبَ بِہَا ٱلۡأَوَّلُونَ‌ۚ وَءَاتَيۡنَا ثَمُودَ ٱلنَّاقَةَ مُبۡصِرَةً۬ فَظَلَمُواْ بِہَا‌ۚ وَمَا نُرۡسِلُ بِٱلۡأَيَـٰتِ إِلَّا تَخۡوِيفً۬ا ﴾

(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).)
