﴿ وَمَا كَانَ رَبُّكَ لِيُهْلِكَ ٱلْقُرَىٰ بِظُلْمٍۢ وَأَهْلُهَا مُصْلِحُونَ ﴾

“For, never would thy Sustainer destroy a community for wrong [beliefs alone] so long as its people behave righteously [towards one another].”

(In truth thy Lord destroyed not) the people of (the townships tyrannously) because of the tyranny they committed (while their folk were doing right) while there were among them those who enjoined good and forbade evil; it is also said that this means: your Lord would not have destroyed the people of the townships through an injustice from Him while their people were doing right, i.e. engaged in acts of obedience and holding firm to them.
