That is because your Lord would not destroy the cities for wrongdoing (6:131)

Almuntakhab Fi Tafsir Alquran Alkarim

Among the set of Allahs correlated principles is His merciful dealing with the guilty who lacked knowledge of what is wrong and what is right, nor has he been guided or warned. Therefore, never would Allah, your Creator, do away with the cities when their inhabitants were unconscious of the wrong they were accustomed to do

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(6:131) (They will be made to bear this witness to show that) it is not the way of your Lord to destroy cities unjustly while their people were unaware of the Truth. *100

That is because your Lord would not destroy the cities for wrongdoing meaning

*100). God does not want His creatures to have any valid reason to complain that He had left them ignorant of the Right Way, and then convicted them of error. God has forestalled any such grievance by sending Prophets and revealing Holy Books to warn both jinn and human beings. If people continue to falter in spite of God's arrangements for their guidance, they themselves are to blame for the punishment they will receive, and they have no justification for blaming their misfortune on God.
