And your Lord would never destroy the towns wrongfully, while their people were doers of good.Allah informs that he does not destroy any town, except that it has wronged itself. No correctional punishment or torment comes to any town, except that its people were wrongdoers. This is as Allah says,وَمَا ظَلَمْنَـهُمْ وَلَـكِن ظَلَمُواْ أَنفُسَهُمْWe wronged them not, but they wronged themselves. (11:101) Allah also says,وَمَا رَبُّكَ بِظَلَّـمٍ لِّلْعَبِيدِAnd your Lord is not at all unjust to (His) servants. (41:46)
