Surah Al-Qasas — Ayah 59 (28:59)
وَمَا كَانَ رَبُّكَ مُهۡلِكَ ٱلۡقُرَىٰ حَتَّىٰ يَبۡعَثَ فِيٓ أُمِّهَا رَسُولٗا يَتۡلُواْ عَلَيۡهِمۡ ءَايَٰتِنَاۚ وَمَا كُنَّا مُهۡلِكِي ٱلۡقُرَىٰٓ إِلَّا وَأَهۡلُهَا ظَٰلِمُونَ ٥٩
English translation (Saheeh International)
And never would your Lord have destroyed the cities until He had sent to their mother [i.e., principal city] a messenger reciting to them Our verses. And We would not destroy the cities except while their people were wrongdoers.
Brief commentary
O Messenger, your Lord did not destroy the cities until he had given opportunity to their inhabitants by sending Messengers to their main cities, just as He sent you to the Mother of Cities. And I was not one to destroy the people of the cities when they were firm on the truth. I only destroy them when they are unjust through disbelief and committing sins.
