(Al-Ahraf) 7 : 5
فَمَا كَانَ دَعْوَاهُمْ إِذْ جَاءَهُمْ بَأْسُنَا إِلَّا أَنْ قَالُوا إِنَّا كُنَّا ظَالِمِينَ

Then their uttering was nothing when Our scourge came to them except they were saying: "Indeed, we were the wrongdoers".

It is told in verse 32: 26 that is it not a Guidance for them the countries Lord destroyed before them, they are walking along with the place of their houses, indeed in it there are Signs, are they not listening?". It is told in verse 50: 36: "How many generations Lord has wiped out before them who were much braver than these are, and stormed through the land, yet had they have any place for escape?". It is told in verse 22: 45: "How many towns Lord has wiped out while they were wrongdoing, they were tumbled down with their roofs, wells were leveled, and palaces lofty". It is told in verse 21: 11: "How many towns which had been wrongdoing did Lord demolish and rose other people in their places?".

 When all the inhabitants became transgressors and wrongdoers, Lord destroyed them by making them witness: “Indeed, we were wrongdoers” as told in verses 21: 14 and 46. Doomsday will occur when all other people belonging to Messenger's community become wrongdoers and transgressors like the Arabic Quran reading Fujjar. See explanation 2: 57; 5: 65-66; 6: 47, and 158.
