﴿ فَكَأَيِّن مِّن قَرْيَةٍ أَهْلَكْنَٰهَا وَهِىَ ظَالِمَةٌۭ فَهِىَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا وَبِئْرٍۢ مُّعَطَّلَةٍۢ وَقَصْرٍۢ مَّشِيدٍ ﴾

“And how many a township have We destroyed because it had been immersed in evildoing - and now they [all] lie deserted, with their roofs caved in! And how many a well lies abandoned, and how many a castle that [once] stood high!”

Before God, people with eyes are those who look at things in order to learn a lesson or draw wisdom from them. Those who see things without learning a lesson from them, are blind in the eyes of God. Their seeing is like that of animals, not human beings. God has spread on the earth innumerable lesson-giving things. Among them are the ancient memorials left behind by past nations. These nations once enjoyed pomp and power, but the signs of their existence today are nothing but a few dilapidated ruins. This reminds everybody of the fate he is finally going to meet. But when people lose the mind’s eye, the eyes on the face will fail to show them anything meaningful.
