Your Lord would never destroy a society until He had sent to its capital a messenger, reciting Our revelations to them. Nor would We ever destroy a society unless its people persisted in wrongdoing.Quran 28:59 [Surah Al-Qasas, The Stories]
Surah al-Qasas [The Story] takes it name from being mentioned in [28:25], ‘Then one of the two women came to him walking with shyness. She said, “Indeed, my father invites you that he may reward you for having watered for us.” So when he came to him and related to him the story, he said, “Fear not. You have escaped from the wrongdoing people.”

This Surah has 88 Ayat.
وَمَا كَانَ رَبُّكَ مُهۡلِكَ ٱلۡقُرَىٰ 
حَتَّىٰ یَبۡعَثَ فِیۤ أُمِّهَا رَسُولࣰا 
یَتۡلُوا۟ عَلَیۡهِمۡ ءَایَـٰتِنَاۚ
وَمَا كُنَّا مُهۡلِكِی ٱلۡقُرَىٰۤ إِلَّا 
وَأَهۡلُهَا ظَـٰلِمُونَ

اور تیرا رب بستیوں کو ہلاک نہیں کیا کرتا 
جب تک ان کے بڑے شہر میں پیغمبر نہ 
بھیج لے 
جو انہیں ہماری آیتیں پڑھ کر سنائے 
اور ہم بستیوں کو ہلاک نہیں کیا کرتے 
مگر اس حالت میں کہ وہاں کے باشندے 
ظالم ہوں
